Deity yoga


Deity yoga is a practice of Vajrayana Buddhism involving identification with a chosen deity through visualisations and rituals, and the realisation of emptiness. According to the Tibetan scholar Tsongkhapa, deity yoga is what separates Buddhist Tantra practice from the practice of other Buddhist schools.
Deity yoga involves two stages, the generation stage and the completion stage. In the generation stage, one dissolves the mundane world and visualizes one's chosen deity, its mandala and companion deities, resulting in identification with this divine reality. In the completion stage, one dissolves the visualization of and identification with the yidam in the realization of sunyata or emptiness. Completion stage practices can also include subtle body energy practices.

Overview

Purpose

The purpose of Deity yoga is to bring the meditator to the realization that the yidam or meditation deity and the practitioner are in essence the same, that they are non-dual. According to John Powers. "Deity yoga is a technique for becoming progressively more familiar with the thoughts and deeds of a buddha, until the state of buddhahood is actualized through repeated practice."
According to Gyatrul Rinpoche, the point of this practice is to "understand your buddha nature, which is the very essence of your being" and is "intrinsically present" in all beings. The fact that the deity is a reflection of qualities already inherent in the practitioner is what makes this practice different than mere deluded or wishful thinking.
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:

Generation stage

In Tantric Buddhism, the generation stage is the first phase of Deity yoga. It is associated with the 'Father Tantra' class of anuttara-yoga-tantras of the Sarmapa or associated with what is known as Mahayoga Tantras by the Nyingmapa. An example of a 'Father Tantra' is the Guhyasamāja Tantra.
The generation stage engages creative imagination or visualization as an upaya or skillful means of personal transformation through which the practitioner either visualizes a meditational deity or refuge tree before themselves in front generation, or as themselves in self generation, to engender an alteration to their perception and/or experience of the appearance aspect of reality. One practices oneself in the identification with the meditational Buddha or deity by visualisations, until one can meditate single-pointedly on being the deity.
According to Tsongkhapa, throughout the various stages of visualization one is to maintain the cognition of emptiness and "one trains in everything to appear as like illusions". Reginald Ray writes that during the process of yidam visualization, the deity is to be imaged as not solid or tangible, as "empty yet apparent", with the character of a mirage or a rainbow.

Four purities

In the generation stage of Deity Yoga, the practitioner visualizes the "Four Purities" which define the principal Tantric methodology of Deity Yoga that distinguishes it from the rest of Buddhism:
  1. Seeing one's body as the body of the deity
  2. Seeing one's environment as the pure land or mandala of the deity
  3. Perceiving one's enjoyments as bliss of the deity, free from attachment
  4. Performing one's actions only for the benefit of others

    Front generation

Front generation is a form of meditative visualization employed in Tantric Buddhism in which the yidam is visualized as being present in the sky facing the practitioner as opposed to the self-identification that occurs in self generation. According to the Vajrayana tradition, this approach is considered less advanced, hence safer for the sadhaka, and is engaged more for the rites of propitiation and worship.

Self generation

Self generation is a form of meditative visualization employed in Tantric Buddhism in which the yidam is invoked and then merged with the sadhaka as an upaya of self-transformation. This is as opposed to the method of front generation. According to the Vajrayana tradition, self generation is held to be more advanced and accompanied by a degree of spiritual risk from the siddhi it may rapidly yield.
An important element of this is "divine pride", which is "the thought that one is oneself the deity being visualized." According to John Powers, "divine pride is different from ordinary, afflicted pride because it is motivated by compassion for others and is based on an understanding of emptiness. The deity and oneself are both known to be empty, all appearances are viewed as manifestations of the luminous and empty nature of mind, and so the divine pride of deity yoga does not lead to attachment, greed, and other afflictions."

Completion stage

The completion stage is the second stage of deity yoga. Completion stage may also be translated as "perfection stage" or "fulfillment mode." In the completion stage one engages in practices associated with the subtle body energies and dissolves the deity into sunyata.
The practitioner can use either the path of method or the path of liberation . At the path of method the practitioner engages in subtle body energy practices. These involve the subtle energy system of energy channels, winds or currents, and drops or charged particles which are said to converge at certain points along the spinal column called chakras. The "wind energy" is directed and dissolved into the heart chakra, where-after the Mahamudra remains, and the practitioner is physically and mentally transformed. At the path of liberation the practitioner applies mindfulness, a preparatory practice for Mahamudra or Dzogchen, to realize the inherent emptiness of every-'thing' that exists.
Jake Dalton uses the terms "practices with signs" and practices without signs". The "practices with signs" are "channels and winds" practices, while in the practices without signs "the enlightened view is accomplished instantaneously, without any effort."

Subtle energy practices

The completion stage employs the "mystic vortices" of the body, the cakra, the subtle energy of the subtle body, the five pranas or vāyu, together with the channels, the nadi through which the energy flows in order to generate the 'great bliss' associated with bodhi or enlightenment. According to Keith Dowman,
According to Berzin,

Sunyata

The completion stage is defined differently in various strands on Vajrayana practice:
