Tattva, often translated as "reality" or "principle," refers to the fundamental nature of existence in various philosophical traditions, particularly in Hinduism and Buddhism. It encompasses the essential truths that underlie the universe, including concepts of Brahman in Vedanta and the nature of emptiness in Madhyamaka Buddhism. In these traditions, understanding tattva is crucial for spiritual growth and enlightenment. It involves discerning the difference between the transient material world and the eternal truths that govern existence. This knowledge helps individuals navigate life and achieve a deeper connection with the universe and themselves.
