Tantra techniques (Vajrayana)


Tantra techniques in Vajrayana Buddhism are techniques used to attain Buddhahood.

Tantra

Vajrayana partially relies on various tantric techniques rooted in scriptures such as tantras and various tantric commentaries and treatises. Tantra is defined as an inner realization that functions to prevent ordinary appearances and conceptions and to accomplish the four complete purities of a Buddha."

Deity yoga

The most important aspect of the tantric path is to 'use the result as the Path'; which means that rather than placing full enlightenment as a goal far away in the future, one identifies with the indivisible three vajras that is, the enlightened body, speech and mind of a Buddha. The practitioner focuses on and identifies with the resultant buddha-form or 'meditation deity', the yidam or 'ishtadevata'.

Symbolism

In order to achieve this self-identification with the yidam, much symbolism, ritual and visualization is used in Buddhist tantric techniques. Tantric techniques may initially appear to consist of ritualistic nonsense; however, it should only be practiced on the basis of a thorough understanding of Buddhist philosophy and strictly following the traditions.

Secrecy

Secrecy is often a cornerstone of tantric Buddhism, simply to avoid harm to oneself and to others by practicing without proper guidance. Full explanation of tantric symbolism and the psychology of the practice is forbidden to the uninitiated, which can easily lead to misunderstanding and dismissal by those who have not been initiated:

Practices

Tantric techniques include:
In the Caryamelapakapradipa, the tantric Aryadeva says to build a three story house. On the third story one "should reside together with the yoginis."
With these women one is to enjoy food, drink and sexual relations:

Guru yoga

The guru or spiritual teacher, in Tibetan Buddhism generally the lama, is essential as a guide during tantric practice. Without the guru's example, blessings and grace, genuine progress is held to be impossible for all but the most keen and gifted. Many tantric texts qualify the Three Jewels of refuge thus: "Guru is Buddha, Guru is Dharma and Guru is Sangha" to reflect their importance for the disciple. In the Vajrayana the guru is considered even more compassionate and more potent than the Buddha because a direct relationship can be had with the guru. The guru also appears in the 'Inner' refuge formulation of the Three Roots, the three foundations of tantric practice.
Guru yoga is a practice that has many variations, but may be understood as a tantric devotional process where the practitioner unites their mindstream with the mindstream of the guru's Three Vajras. Guru yoga is akin to Deity yoga since the guru is engaged as the yidam, or meditational deity, a nirmanakaya manifestation of a Buddha. The process of guru yoga generally entails visualization of a refuge tree as an invocation of the lineage, with the root guru channelling the blessings of the refuge tree to the practitioner. It might involve visualization of the guru above or in front of the practitioner. Guru yoga may also entail a liturgy or mantra such as the Prayer in Seven Lines, an evocation and invocation of Padmasambhava, though this is neither necessary nor mandatory.

Deity yoga

Deity yoga is the fundamental Vajrayana practice, involving a sadhana practice in which the practitioner visualizes himself or herself as the meditation Buddha or yidam of the sadhana.

Purpose

The purpose of Deity yoga is to bring the meditator to the realization that the deity and the practitioner are in essence the same, non-dual. The yidam generally appears in a mandala and the practitioner visualizes himself or herself and their environment as the yidam and mandala of their Deity Yoga practice. This visualization method undermines a habitual belief that views of reality and self are solid and fixed, enabling the practitioner to purify spiritual obscurations and to practice compassion and wisdom simultaneously:

Visualisation

Representations of the deity, such as a statues, paintings, or mandalas, are often employed as an aid to visualization in both the Generation Stage and the Completion Stage of Anuttarayoga Tantra. The mandalas are symbolic representations of sacred enclosures, sacred architecture that house and contain the uncontainable essence of a yidam. In the book, The World of Tibetan Buddhism, the Dalai Lama describes a mandala: “This is the celestial mansion, the pure residence of the deity.”

Yidams

In the Vajrayāna Buddhism of Tibet and East Asia, which follow the Nālandā Tradition of India-Tibet-China, there are fifteen major tantric sādhanās, each connected with a specific yidam:
  1. Śūraṅgama
  2. Sitātapatrā
  3. Nīlakaṇṭha
  4. Tārā
  5. Mahākāla
  6. Hayagrīva
  7. Amitābha
  8. Amitāyus
  9. Bhaiṣajyaguru
  10. Akṣobhya
  11. Guhyasamāja
  12. Vajrayoginī
  13. Vajravarāhi
  14. Heruka
  15. Cakrasaṃvara
  16. Yamāntaka
  17. Vajrabhairava
  18. Kālacakra
  19. Hevajra
  20. Chod
  21. Vajrapāṇi.
All of these are available in Tibetan form, many are available in Chinese, and some are still extant in ancient Sanskrit manuscripts.

Mandalas

Mandalas are used as an aid in realizing the inner ground:

Parinamana

The dedication of merit is a standard component in Vajrayāna sādhanās.

Luminosity yoga

or Clear light, in Vajrayana, Tibetan Buddhism and Bon, refers to the nature of mind experienced in deep sleep and death.
Patrul Rinpoche defines ground luminosity as the:
The practitioner trains to consciously enter the deep sleep state. If one has the ability to remain conscious during deep sleep, one will be able to recognize the luminosity of death and gain Buddhahood. This is called the meeting of mother and child luminosities, resulting in the state of thuktam at death.

Sexual yoga

Karmamudrā is sexual practice with a physical or visualized consort. It cannot be practiced without the basis of the inner heat yoga, tummo, of which karmamudrā is an extension. This sadhana is a part of the Six Yogas of Naropa, Lamdre, Kalachakra and Anuyoga. The practice is represented in yab-yum imagery.
All traditions agree that qualified lay practitioners can use physical consorts as the Vajrayana founders did. For example, Atisa wrote that "Those on which the householder may rely include everything taught in the tantras." There are different stances on whether current monks can engage in the practice. The Buddhist scholar Tripitakamala felt the overall goal of Buddhahood overrides concerns for monastic vows.
