Yoga Vasistha, or the Divine Yoga of the Sage Vasistha. Vol. 1, 2

"Yoga Vasistha" is a unique work, one of the key texts in ancient Indian philosophy of yoga and Advaita Vedanta. The teachings of Sage Vasistha allow one to apply wisdom tested over the centuries in practice.
The book is a collection of dialogues between sages and Prince Rama. The prince's questions pertain to all aspects of human life, and the answers of Sage Vasistha boil down to the idea that everything is a manifestation of infinite Consciousness, including the material world, i.e., the world as we see it.
In this teaching, Vasistha revealed the secret methods and philosophy of the Vedas. It brings great benefit not only to serious spiritual seekers, religious figures, philosophers, and scholars, but also to ordinary people who are interested in building normal relationships with others and themselves, who wish to achieve harmony and are ready to taste the fruits of eternal Truth.
This book is a methodological guide to achieving the state of Enlightenment.
