Vijñāna Bhairava Tantra

The Vijñāna-bhairava-tantra (VBT, sometimes spelled in a Hindicised way as Vigyan Bhairav Tantra) is a Shiva Tantra, of the Kaula Trika tradition of Kashmir Shaivism, possibly authored by Guru Keyūravatī. Singh notes that it is difficult to establish an exact date for the text, and it could have been written at some time from the 7th to the 8th century CE. It is also called the Śiva-jñāna-upaniṣad by Abhinavagupta.

The VBT is framed as a discourse between Bhairava (the "fearsome one", or "the dark matter") and the goddess Bhairavi in 163 Sanskrit anuṣṭubh stanzas. It briefly presents around 112 Tantric meditation methods (yuktis) or centering techniques (dhāraṇās) in very compressed form.

These practices are supposed to lead to the recognition of the true nature of Reality, the "tremendous" or "awesome" consciousness (i.e. vijñāna-bhairava). These include several variants of breath awareness, concentration on various centers in the body, non-dual awareness, mantra practice, visualizations and contemplations which make use of the senses. A prerequisite to success in any of the practices is a clear understanding of which method is most suitable to the practitioner.

Overview
The text presents itself as containing the essence of the Rudrayamala-tantra, a Bhairava tantra that is now lost. In the Vijñāna-bhairava-tantra (VBT), Bhairavi, the goddess (Shakti), asks Bhairava (the fearsome manifestation of Shiva) to reveal the essence of how to realize the true nature of reality. In his answer Bhairava describes 112 ways to enter into the universal and transcendental state of consciousness. References to it appear throughout the literature of Kashmir Shaivism, indicating that it was considered to be an important text in this tradition.

The VBT describes the goal of these practices, the "true nature of reality", as follows in the Christopher Wallis translation from 2018: "Beyond reckoning in space or time; without direction or locality; impossible to represent; ultimately indescribable; Blissful with the experience of that which is inmost; a field of awareness free of mental constructs: that state of overflowing fullness is Bhairavī, the essence of Bhairava. It is that essence which is ultimately real & fundamental; it is that which ought to be known & experienced; it is that which is inherently pure, and it is that which pervades everything."

According to Christopher Wallis, Bhairava and Bhairavi are also used to refer to expanded states of consciousness, with Bhairavi referring more to energetic and active (śakti) states, and Bhairava referring to still and quiescent (śūnya) states. Wallis also notes that the text exhibits a "strong Buddhist influence", and one of the most common meditations taught in the text focuses on the ‘voidness’ (śūnya) of things, such as verse 48 which offers a meditation on the body as empty space, and verses 45 and 49 which teach meditations on the empty space of the heart.

Practices
Most of the VBT's verses are brief compressed descriptions of various practices that allow one to access the state of Bhairava consciousness. Mark Dyczkowski has classified the practices of the VBT into various main types along with the verses in which they appear:

Commentaries and English translations
The text appeared in 1918 in the Kashmir Series of Text and Studies (KSTS). The Kashmir Series published two volumes, one with a commentary in Sanskrit by Kshemaraja and Shivopadhyaya and the other with a commentary, called Kaumadi, by Ananda Bhatta.

In 1957, Paul Reps brought the text to wide attention by including a poetic English translation in his popular book Zen Flesh, Zen Bones. Reps' translation was the subject of a voluminous commentary by Osho.

As the Sanskritist Christopher Wallis writes, many of English VBT translations have been done by persons who lack training in reading Sanskrit and who lack the background of reading the sanskrit tantric texts that the VBT relies on. The result has been various poetic or free form renderings which fail to properly communicate the actual practices which are briefly outlined in the text. Two exceptions to this are Jaideva Singh's translation and Mark Dyczkowski's translation.
