Mahanirvana Tantra: Tantra of the Great Liberation

The best known of the Tantric scriptures. It was translated by Sir John Woodruffe (under the pseudonym 'Arthur Avalon'), one of the few Indologists to gain direct access to this obscure and secretive branch of Hinduism. Framed as a conversation between the god Shiva and goddess Shaki, this text describes the chakra, or subtle energy structure of the human body, ceremonies, yogic practices and mantras for meditation, and a summary of the Hindu laws (dharma) regarding sexual behavior. The text of the Mahanirvana Tantra has been suspected to be partially or completely fabricated by Hariharanandanatha to support his reformist views, and apparently dates to the 18th Century A.D. This is not to say that it is invalid, just that it is a comparatively recent text which puts forward an unorthodox branch of Hinduism. This should be kept in mind when reading it.
