Tamil Siddhas, a loosely associated group of mystics belonging to the pan Indian Tantric tradition, recommend using the body and the mind as tools to surpass limited existence. They prescribe a method of yoga which utilizes the mind’s power to bring together dualities within a practitioner’s body to achieve kāya siddhi or a perfected, deathless body. The esoteric language and symbolism that the Siddhas use to convey their teachings have led to the misunderstanding and misinterpretation of their philosophy and methodology. (...) This study aims to explain Tamil Siddha yoga and dispel some of the misconceptions about Tamil Siddhas using Siddha Agatthiyar’s composition, Antaraṅga dīkṣā viti, as the primary text. (shrink)
