Tattvabodha literally means 'Knowledge of the Ultimate Truth.' It is a complete and in-depth introduction to the basic tenets of Non-dual (Advaita) Vedanta. This is a fundamental text for those desirous of moksha (freedom from the sense of limitation centered on the egoic ‘I’). Its value is to present succinct definitions of some key terms in Advaita Vedanta. It also unfolds the 4-fold classical disciplines (Sadhana Chatushtaya) that converts an average student into a qualified seeker of Self-Knowledge. This small but all-encompassing Prakarana Grantha (introductory text) of Non-Dual Vedanta has been written by our lineage ancestor Sri Adi Shankaracharya. He is regarded in India as the Avatar of Lord Shiva himself, an embodiment of the timeless and immortal vision of the Vedas.
