Śrī Ātmabodha
Śaṅkara's sixty-eight verses on the knowledge of the Self: why knowing ends bondage where doing cannot, told through the rope and the snake, the water and the salt — and closing in the Self as Brahman, one's own.
All sixty-eight stanzas rendered into Tamil veṇbās by Bhagavān in 1948, keeping the treatise's own order.
