Jnana refers to the concept of knowledge in various philosophical and spiritual traditions, particularly in Hinduism and Buddhism. It emphasizes the understanding of reality, self-awareness, and the nature of existence. Jnana is often seen as a path to enlightenment, where individuals seek to gain insight into the true nature of the self and the universe. In the context of Vedanta, a school of Hindu philosophy, Jnana is considered essential for liberation from the cycle of birth and death. It involves the study of sacred texts, meditation, and self-inquiry, allowing practitioners to discern the difference between the eternal self (Atman) and the temporary physical world (Maya).
