In Hinduism, Advaita Vedanta and the Yoga Vasishtha both explore the profound concept of non-duality and the ultimate nature of reality. Advaita Vedanta is based on the idea that Atman (the individual self) and Brahman (the ultimate reality) are one and the same, despite the apparent multiplicity that veils this truth. The famous statement "Tat tvam asi" ("You are that") from the Chandogya Upanishad expresses this essential unity, affirming that the individual being is none other than the absolute.

The Yoga Vasishtha, on the other hand, offers a practical and philosophical reflection on the nature of the universe and the inner quest. It encourages deep inquiry with questions such as "Who am I?" and "How did this universe come into being?" while cultivating a certain detachment from worldly illusions. This text advises seeking the company of enlightened beings, upholding an ethical life, and remaining aware of mortality as motivations to transcend the limited identification with the body. By turning inward, the wise person discovers the infinite consciousness that underlies the entire universe. The same light that shines in the sun also illuminates the smallest being, revealing a single consciousness that animates all aspects of existence.

Together, these teachings offer a path toward the realization of non-duality, where the individual recognizes that their true essence is one with the All.
