The three samayas are like a bridge which spans from the shore of the lower
        three yogas to that of Anuttara Yoga. Samaya means oath: once it has been declared,
        it must always be kept by the practitioner. For one who has not declared such
        samayas, there is no question of keeping or not keeping them. Nevertheless,
        one who intends to be an Acarya of either the lower three yogas or of Anuttara
        Yoga ought to declare these three samayas when the initiation of Acarya is
        given by his Guru, lest he has no chance again for the same. 
      The last section dealt with the Three Samayas which in some Tantric sources
        are said to have been laid down by the Sambhogakaya. This section concerning
        the fourteen root-fallings was laid down by the great Bodhisattva Asvaghosa
        who had gathered them from the Tantras and the sayings of the ancient Tantric
        sages. Hence they should be treated as reliable and reasonable rules laid down
        by Buddha Gautama himself. In Tibet, both the new party and old parties have
        accepted them without any doubt. 
      
        1. Provisions and Explanations Concerning Disparagement of the Vajra Acarya 
        a) What does the Vajra Acarya mean? 
        Acala means immovable. Acarya contains the same root and thus means one who
          should always be respected as a Buddha by one who once has taken refuge from
          him. There are different kinds of Acaryas. The heavy punishment of falling
          into Vajra-Hell is only concerning the last and highest one as mentioned below. 
        
          - The Acarya from whom the disciple has taken refuge in general is like
            the King of the Kingdom. 
- The Acarya from whom the disciple has gotten the Silas of Hinayana or
            Mahayana is the guide of Dharma and one's uncle. 
- The Acarya from whom the disciple has gotten the Initiations and Silas
            of Vajrayana is one able to impart the methods of getting the attainment
            of Buddhahood in this lifetime and is like one's father. 
- The Acarya before whom the disciple has confessed his sins and from whom
            one has received the renewed initiation is like a mother. 
- The Acarya from whom the disciple has received the great initiation of
            the Liberation Path such as the Great Perfection or the Mahamudra is like
            one's eyes. 
- The Acarya from whom the disciple has received all the important and
            highest instructions and who is enabled to bless disciples to get the Attainment
            of Vajra-Dhara in this life-time is like one's heart. 
Among the six kinds of Acarya introduced above, those of (1) and (2) are not
          Vajra Acarya, the other four are. But the punishment of falling into Vajra-Hell
          is only dealt out to the disciple who has severely disparaged his Acarya of
          the last and highest kind. 
        b) What kinds of sins are covered under the term of "Disparage"? 
        According to the explanations of the great guru Naropa, which were imparted
          to me by my guru Kunga Rimpoche, there are six kinds of sins covered under
          the name of disparagement: 
        
          - Killing the Acarya without reasons and conditions. 
- Taking the wife of the Acarya as a Dakini without the permission of the
            Guru. 
- Making the body of the Acarya unhappy, painful and toilsome. 
- Taking or robbing food or any kind of wealth of the Acarya without permission. 
- Hiding the merits of the Acarya and laying criticism on his party, action
            or rule and saying that his good things are bad. 
- Leaving the Acarya from whom the disciple has received esoteric Dharmas
            and afterwards getting teachings from another Acarya saying that he did
            not get any instruction from the previous Guru. 
Although all these six kinds of sins are considered disparagements, yet the
          falling punishment is dealt out to the sinner who has committed the first two
          kinds of sins, i.e. taking the Acarya's wife and killing the Acarya. 
        2. To Oppose and Disregard the Teachings of Buddha. 
        What kinds of possibilities of disregarding are considered sins under this
          provision and among them which one is the particular one to watch out for? 
        
          a) Non-belief on the reasonable Truth. 
          b) Agreement with the false views of outsiders. 
          c) According to the great Guru Naropa's explanation, the greatest sin may
            be in this case that the disciple does not recognize the rules laid down in
            a secret description and considered the inverse, such as frequenting others'
            wives. This does not mean any wives of others but particularly Nairatamya or
            her Incarnations who is and are wives of all skilled practitioners. 
        
        In my opinion, the third one above, c), is the particular one which must be
          watched out for. Regarding the first two a) and b), they are in general forbidden
          in previous course of Silas. 
        3. To Struggle with Vajra-Brothers 
        a) What does Vajra-Brother mean? 
        
          - Ordinary Vajra-Brothers: Those who have learned the doctrines of Vajrayana
            are Vajra-Brothers to one another. 
- Near Vajra-Brothers: Those who get the initiation from the same Guru
            are near Vajra-Brothers to one another. 
- Special Vajra-Brothers: Those who get the initiations under the same
            Guru in the same Mandala at the same time are special Vajra-Brothers to
            one another. 
b) What does the struggle mean? In general, any struggle caused by one's inner
          sorrow of anger is included, but particularly, in my opinion, is the special
          struggle not pointed out by the great Guru Naropa which is caused by snatching
          at a Dakini who has already been occupied by another Vajra-Brother. 
        4. To have no compassion for a sentient being. 
        What kind of sentient being does this mean? In general any sentient being
          is included, but particularly it is the person who asks for the favouring blessing
          in the third initiation sense, and who the practitioner refuses because he
          or she is too old or too ugly. It is my humble opinion that all the failings
          of the Tantra Silas are concerned with the third initiation, otherwise the
          sila would belong to the Mahayana. 
        5. To cut off the roots of the Right Dharma--Bodhicitta. 
        a) What kind of Bodhicitta does this mean? In the commentary our great Guru
          taught us about three kinds of Bodhicitta as follows: 
        
          - Worldly Bodhicitta of Good Will and Conduct. 
- Kunda Bodhicitta--the enlightened drops (transmitted from semen). 
- Bodhicitta of Sunyata-Light. 
b) In my humble opinion there are five kinds of Bodhicitta covering all of
          those mentioned in different Tantras and Sutras, although they have not been
          systematized. Since I emphasize the whole system of Buddhism in the Three-Yanas-in-One,
          I have arranged them in the following order: 
        
          - Bodhicitta of Good Will. 
- Bodhicitta of Good Conduct. 
- Bodhicitta of Victorious Significance (e.g. the Sunyata-Light). 
- Bodhicitta of Samadhi in the lower three yanas has been emphasized by
            the great Bodhisattva Nagarjuna. 
- Bodhicitta of Kunda in the Anuttara Yoga. 
Among all these five are included the three from a) above. Although falling
          into the Vajra-Hell is dealt out to only those abusing the last kind, 5)
          above, all the five are connected. 
        c) What does the term "cut off" mean here? It means that the practitioner
          discharges his holy semen--the Kunda Bodhicitta--without any special reason,
          only by his negligence and lustfulness. This is a great sin which might cause
          the Dakini to weep. 
        6. To slander the Dharma of different schools inside and that of outsiders. 
        A lot of ancient commentaries on this provision were given, such as detracting
          from the false Dharmas of outsiders as they have no benefit for final liberation
          yet they are teaching men how to do good; or as undermining the Hinayana by
          saying their foundation is not good and cannot get one quickly to the thither
          shore, yet they are a good foundation for Mahayana and Vajrayana and include
          the personal teachings of Lord Gautama; or as backbiting the secret Dharma
          of the third initiation even of one's own school yet it is a very sacred and
          secret Dharma of Vajrayana which has its own profound philosophy and methods
          of the consequence position of Buddhahood. Hence all these Dharmas should be
          respected with deep devotion. In general, none of them should be slandered,
          the sinner may fall into the Vajra-Hell. 
        Again it is also said that when the teacher who has great compassion to help
          his disciples progress in the Dharma, he may give some comparative instructions
          to them concerning what is lacking in the Hinayana and what is the complement
          to this lack in the Mahayana and Vajrayana. This is not a sin at all as Buddha
          Gautama himself has done this more than once. 
        7. To teach the Secret Dharma to one whose faith has not matured. 
        
          a) What does the Secret Dharma mean? The doctrine which never appears in the
            Mahayana or the Prajna Paramita and in the lower three yogas is of the Secret
            Dharma for one whose wisdom is not enough to recognize its profound philosophy.
            All the theories and methods concerning Evolutional Yoga, Perfect Yoga, Karmamudra,
            Vajra-love, the five meats, five nectars, and skull-made instruments are included
            in the term Secret Dharma. 
          b) What kinds of faith are those which are modified by the term "not
            matured". There are four kinds of faith which are qualified with the term
            of "not matured." 
          
            - The unmatured faith of spiritual foods. Here by spiritual foods is
              meant the inner and outer initiations. One who has not received these
              initiations, has not mature faith. 
- The unmatured faith of all rituals and instructions. One who has not
              received these rituals and instructions concerning the practical necessity
              of the four great initiations, does not have mature faith. 
- The unmatured faith caused by committing sins and falling. 
- The unmatured faith caused by non-confidence in the secret Dharma. 
c) In addition to the above four kinds of unmatured faith, I should mention
            unmatured faith relative to the Period. In the ancient pure orthodox doctrine,
            the secret Dharmas of Vajra-love were very seriously kept in secret, even a
            Vajra was not allowed to be seen by others. This was in the period of the Buddha's
            lifetime. In the period of symbolism or scholasticism, the Vajra and Vajra-bell
            and images of Heruka form were in an erotic aspect and eventually appeared
            in temples and on pagodas. Now it is the Kali-age; communication has been widely
            opened, and one may pilgrimage to every religious holy place within the whole
            world by aeroplane within a few days. A race among all the religions to select
            the one international public religion is going on. Hence the secret and sacred
            Dharma of every religion has been promoted and spread all over the world and
            there is no religion keeping its essential Dharma secret again. Many secret
            doctrines of Buddhism have been introduced to the West. The most important
            Tantra of Hevajra has been translated from its texts of Sanskrit and Tibetan
            and is sold by the Oxford University Press. My dear readers, would you please
            tell me how to keep it in secret again? 
          d) It was foretold by our great Guru Padmasambhava that his secret Dharma
            would be widely spread all over the world when the iron bird is flying in the
            skies, therefore I can not help but call this a matured period and the last
            two periods unmatured. Our main duty in this period is not keeping secret but
            saving the rules or the fallings which concern the secret Dharma of the Vajra-love
            by emphasizing them. It is my humble opinion that no matter whether this is
            a matured period or not, this Secret Dharma is not theory but fact and should
            appear, be translated into English, and be supplied in the marketplace so that
            every country may get it. 
        
        8. To Disregard the Entity of the Five Aggregates of the Body which Contain
          the Nature of the Five Buddhas. 
        To make the explanation more clear, a comparative list is offered below: 
        
          Body Aggregates Buddhas 
            PANCASKANDHA PANCABUDDHAS 
          Rupa (form) Aksobhya 
            Vedana (feeling) Ratnasambhava 
            Sannjna (thinking) Amitabha 
            Samskara (Action) Amogasiddhi 
            Vijnana (Consciousness) Vairocana 
          PANCABHUTANI PANDAKINI 
            Apas (water) Eastern dakini 
            Prthivi (earth) Southern dakini 
            Jyotis (fire) Western dakini 
            Vaya (air) Northern dakini 
            Akasa (space) Central dakini 
        
        Although this provision only mentions the five Buddhas, yet usually in other
          sources these five are always accompanied by the five Dakinis whom I have also
          mentioned in the above list. 
        The ways to disregard one's own body as mentioned in the ancient commentaries
          are suicide or homicide by any means, beating the heart or breast, slapping
          the face, pulling out hair and all kinds of actions causing oneself to suffer. 
        In my opinion, this matter is not so simple. First of all, one should distinguish
          between the three kinds of our "body", from gross to subtle. The
          flesh body which is born from our past profane karmas is relevant to the
          ascetic or Dhuta practice, and although through it the body is made to suffer,
          yet this does not actually constitute this falling. The second body may be
          called the meditative body which is a meditative result and an inner body
          of heaven in eight stages corresponding to the eight Dhyanas and also a body
          of the ten Bhumis of Bodhisattvas which is relevant only to the practice
          of Mahayana. As such, this body may be made a victim for the purpose of saving
          others in accordance with a Bodhisattva's practice and not constitute this
          falling of Vajrayana. The last and highest one is a body in Buddhahood through
          the practice of Evolutional Yoga. Thereby the realization of a Buddha body
          has been accomplished and it should be recognized as a Buddha or Dakini or
          Heruka body toward whom any kind of disregard done might relate to this very
          falling. However this kind of falling is still not the one particularly emphasized. 
        The falling in question occurs, in my opinion, in relation to the Tantric
          practitioner who is enabled to practice Vajra-love. This pertains to the Perfect
          Yoga with stress lying on the four stages of performance and the identification
          of four Tantric Voidness and four secret Bliss. The falling occurs when such
          a practitioner is acting too much in the descent stage or too much in the ascent
          stage or too much in the four Voidness meditations or too much in the four
          Bliss meditations. Either of these partial acts are a kind of disregard for
          its opposite. It is as if killing their own wisdom-life. Until and unless the
          practitioner can keep them in equilibrium balance, he can not get rid of this
          kind of falling which is falling into transmigration but not hell. 
        9. To Doubt all the Dharmas which are Pure in their Nature. 
        What are those Dharmas? This question has been answered by our Great Guru
          Naropa. The five meats are of man, cow, dog, horse and elephant; the five nectars
          of great incense are urine, stool, the white wisdom drops (semen), the red
          wisdom drops(ovum), and the pleasure drops, that is the brain-marrow. These
          have been pointed out by this sage. 
        The five nectars surely are not those of a common person's but of those sages
          even whose excrement has a very good smell. These are associated with the five
          Buddhas, as listed below: 
        
          Five Meats Five Nectars Five Buddhas 
            Man's flesh urine Aksobhya 
            Cow's flesh Stool Vairocana 
            Dog's flesh Red Ovum Ratnasambhava 
            Horse's flesh White semen Amitabha 
            Elephant's flesh Marrow of brain Amoghasiddhi 
        
        Besides these should be added those secret Dharma-instruments which are made
          of human bones such as the nectar bowl, and the ornaments of a Heruka which
          are made of human skulls. 
        Again, the wrathful Yidam and his Homa by which a demon or human foe may be
          killed are both easily to be doubted. However, the particular falling sin is
          dealt out to the practitioner of Vajra-love. Such a one who although he has
          received the great initiations still in his inward thoughts keeps such a doubt
          that the lustful practice of Vajra-love might not be pure, his is the very
          great sin of falling. 
        10. To Have Great Compassion toward the Poison. 
        According to the commentary of the great Guru Naropa, there are two kinds
          of poison. One is the person who keeps the poison outwardly thereby rebuking
          or slandering the believers of the third initiation; the other is the person
          who keeps the poison inwardly as to indulge in the love actions without identification
          with the voidness. He who sides with either of these two kinds of persons or
          who himself commits the same is the very sinner of the provision. 
        11. To Distinguish All Dharmas which are Without Names in Nature. 
        Here in this provision the modification of the term "in nature" should
          be paid more attention to as it is a term expressing the Dharmakaya with its
          characteristics of equilibrium and silence. Suppose the term which is in need
          of being distinguished is "in form" or "in condition",
          then the more you distinguish them, the more you are able to make their meanings
          obvious. Buddha Gautama had taught us different yanas and Dharmas, some are
          of low knowledge, some are high, some are exoteric, some are esoteric. Among
          these, Buddha himself had distinguished what reached half of the Truth, and
          what reached the whole Truth. Was he a sinner of this falling? Certainly
          not! In the Lotus-Sutra the Buddha had divided all his teachings into three
          kinds of carriages: sheep carriage, deer carriage and bull carriage. According
          to this the Tien-Tai School divided the teachings into five periods: The
          Avatamsaka was the first period, like fresh milk; the Agamas the second period,
          like coagulated milk; Vaipulyas the third period, like curdled milk; Prajna
          Paramita the fourth period, like butter; and the Lotus and Parinirvana the
          final, like clarified fine butter. Were these differentiations made by the
          Tien-Tai School a kind of falling? No! 
        Hence a distinguishment held to in nature is a falling, while a distinguishment
          held not to the form is foolish. We should recognize that the difference
          is one-sidedly held to only in the Dharmarupa but not in the Dharmadhuta.
          One who desires to learn Buddhism must know all the differences such as the
          three knowledges, the twelve styles of teaching in the Tripitaka, the one
          hundred Dharmas in the Idealistic School, many a group of ten numbers of
          Dharmas in the Avatamsaka Sutra, besides all these Dharma knowledge, all
          the differentiations of realization in the position of consequence such as
          the five wisdoms, six supernatural powers, ten Buddha's powers, five kinds
          of eyes, eighteen distinguished Buddha Dharmas, four kinds of Bliss, four
          kinds of Voidness, four or five kinds of Buddha bodies. All those Dharmas
          collected in "The Encyclopedia of
          Dharma-Numbers" from the least number to the greatest number should
          be discriminated very skillfully. 
        To hit the mark of this falling and understand it, it should be pointed out
          that one who has received the third initiation but who still keeps some differentiation
          in his mind as to prefer the great perfection and the Mahamudra as purer than
          the Vajra-love treats the latter as a way of defilement. This is the very sin
          of falling. 
        Regarding the Guru's teaching, the Guru may distinguish the third initiation
          from the fourth but not the disciples, that is to say the chaff is one thing
          to the wheat and a different thing to sheep and goats. 
        12. To Slander the Believer who has Faith in the Secret Dharma. 
        This secret Dharma is exactly the Vajra-love and none other. It is a matter
          of fact that one who practices such a kind of secret and sacred Dharma is often
          slandered by the one who believes the way to liberation is only through the
          Mahamudra. The ordinary Buddhist who has never received teachings in the Anuttarayoga
          will also slander those believers of Vajra-love. This may be an obstacle to
          his own course of learning in Vajra-love in the future when he awakens to the
          virtue of this secret Dharma yet it will then be a falling to him. 
        To keep the secret Dharma under lock and key only benefits the person whose
          faith has not yet matured and should not be done to increase one's own pride
          and stinginess. I do not agree with the ancients in their commentaries that
          this sin discussed in this provision also should include slander to the believers
          of Mahayana and Hinayana due to the fact that such sins have been forbidden
          in the Silas of Mahayana. 
        13. To Neglect Practice of the Dharma which has been obtained by Samaya. 
        Here the Dharma referred to particularly concerns Vajra-love. In fact, most
          of the disciples who receive all of the four initiations in one or two days
          have only a general faith in Anuttarayoga and no faith in Vajra-love. After
          their initiation, they never practice it. Some of them, having awakened to
          the dangerous conditions involved in Vajra-love, leave it half-way. Both are
          sinners of this falling. Hence in my humble opinion, as has been described
          in my Chinese work, all four of these initiations should be given separately. 
        14. To Slander the Nature of Wisdom Shown by a Dakini. 
        Today is the date of the 25th of the ninth month of the Wooden-Dragon year
          according to the Tibetan Lunar Calendar. It is a holy date of offering and
          praying to the Vajra-Yogic mother according to the rules of my hermitage. Among
          all the provisions in this section, this last but not least is a very important
          one which may help us to honour our Mother who was, is, and will be the Producer
          of Buddhas. I have written a ritual to her in which I emphasize her gnostic
          body and her compassionate heart. 
        Every pore of her body is a manifestation of her wisdom which we should worship
          and praise. All of her manners mentioned in the Hevajra Tantra, i.e. passion,
          heroism, loathesomeness, horror, mirth, frightfulness, compassion, wonderment
          and tranquility, all nine of these emotions are expressing her wisdom. To identify
          her great Pleasure shown through all of her manners with our Voidness is Samadhi
          and is the closest course to our final Enlightenment. Hence one who slanders
          her in any way by any means falls. Envious is he who sees her lovely manner
          only toward others; foolish is he who treats her horror as a common sorrow,
          and thereby he slanders her and commits the sin of falling. 
      
      This was written about by the great Bodhisattva Nagarjuna in two stanzas which
        I now translate as follows: 
      All these eight great sins are connected with Vajra-love. The first and third
        ones are very clear in their provisions. The second one regarding struggle
        and the sixth one, staying with monks, both are for the case of the Dakini.
        The preaching mentioned in the fifth and eighth are both concerning Vajra-love.
        The fourth one regards not imparting when one should, and the seventh being
        too proud. All are concerning the same Vajra-love doctrine. Those Gurus who
        impart the third initiation to every disciple but keep the Vajra Silas to themselves
        are like training the disciples to box but keeping in secret the medicine to
        cure the wounds caused by boxing. This is very foolish. 
      These silas were written in one and a half stanzas by the sage Gaya. 
      Each provision of the above silas contains some subject of good Karma, outward,
        inward, and secret in the position of salvation. Outward Karmas connect with
        Hinayana, inward with Mahayana, and secret with Vajrayana. The last one is
        the very provision concerned. 
      Referring to 1) above: Good Will here means desiring Full Enlightenment within
        this lifetime. Good Conduct here means practicing Vajra-love with a Dakini.
        The Three Silas here mean restraining by anthropomorphic care of the third
        initiation leading to good Dharmas by practicing the Ewan-yoga and profiting
        others by the good Karmas held in the Lotus Altar. 
      Referring to 2) above: Vajra here means the Buddha's expedient Lingam, i.e.,
        the productive organ in the form of vajra. The Bell is the productive organ
        of the wisdom yogini in a lotus and bell form; Mudra is their union in a Heruka
        form. 
      Referring to 3) above: The wealth of Bindu (Kunda Bodhicitta), Dharma of wisdom
        fire, and the no-fear of Heruka-action are the three kinds of almsgiving. 
      To draw all the wisdom-energy into the medium nerve and achieve the everlasting
        instructions is the perfect speech of Amitabha. 
      Referring to 4) above: The identification of "Ewan" yoga along with
        its four kinds of great pleasures to offer the Buddhas and give alms to all
        sentient beings in one's illustrious holy light is the essential Karma of the
        northern Buddha. 
      Although all these subjects of good Karma should be done by every Buddhist,
        they are quite different when done by the five Buddhas. The practitioner should
        keep the following realizations so that the distinguished Karma of Buddhas
        might be clarified: these are referring to the 5) above. 
      All the above three points are my own opinion which must be grasped for one
        to become aware of the differentiations between the Karma of Mahayana and that
        of Vajrayana. 
      Besides the similarity between the explanation for these last five and those
        for the Five Silas of the Buddhas, I ought to mention the important points
        of these five Silas of Dakinis. They lay most stress on the material flesh
        of the Dakini. That is why the Tibetan ancients emphasized that a Dakini in
        a human body was better than one in a divine body or a spiritual body for the
        practice of Vajra-love. The five kinds of meat should be taken along with other
        nourishment such as milk. Just as in Milarepa's good example, he was able to
        take only herbs during his daily practice, nevertheless, when he almost accomplished
        his practice, he was advised by secret instructions prepared for him by his
        Guru Marpa that he should then take nourishment. Suddenly he was fully enlightened
        after he took the nourishment. Surely the highest philosophy of Buddhism is
        penetrating into the lowest lustful flesh and the deepest sorrow concerning
        flesh should be sublimated by the heights of Truth. Then the polarized reality
        can be harmonized as a whole Truth. To draw a worldly instance, it is like
        seizing robbers within their hiding place and cleaning them up thereby. By
        hiding away from the robbers as in Hinayana or by discharging the confined
        robbers with great compassion as in Mahayana, neither could stop their robbing
        minds. 
      These four terms are seen in the Nyandi-yoga, the highest doctrine of Nyingmapa.
        They have been used as four conditions of the Great Perfection. As I try to
        make every Dharma into a whole system in my emphasis on Three-Yanas-in-One,
        the Silas or Vinayana should be part of this whole system too. From Hinayana
        to Mahayana and again to Vajrayana I have introduced to the West. The Silas
        of Mahamudra or the Great Perfection should not be omitted. Hence these four
        have been taken for this purpose. I have written a Chinese work on the subject
        of Silas of Nature from which some extracts have been translated below. They
        might serve as an explanation for these four silas: 
      Because every Dharma has non-reality, there would be non-holiness which should
        be grasped. There would be non-goodness which should be renounced and non-badness. 
      Because every Dharma by nature is vast, there would be non-selfishness. The
        pleasure would not only be within one's self; the pain would not only be without
        one's self. 
      Because every Dharma by nature is alone, there would be non-subjects and non-objects.
        Harmness would have no object to be given to. Advantages would have no subject
        to be kept for. 
      Because every Dharma by nature is natural, there would be no silas to keep
        and no sins to reject. 
      These four silas are for the Practitioner of Mahamudra, the Great Perfection,
        or Zen. Although he is beyond the silas, by nature he should not refuse them,
        and naturally he has to identify with them.
