The Four Vedas
The oldest scriptures of Hinduism and the foundation of Sanatan Dharma — composed over 3,500 years ago, containing the eternal knowledge of the universe.
The word Veda comes from the Sanskrit root vid (to know). The Vedas are Shruti— "that which is heard" — considered to be of divine origin, revealed to ancient rishis during deep meditation. They are the oldest surviving literature in any Indo-European language and form the foundation of Hindu philosophy, ritual, astronomy, mathematics, medicine, and music.
Each Veda has four layers: Samhita (mantras/hymns), Brahmana (ritual commentary), Aranyaka (forest texts for meditation), and Upanishad (philosophical conclusions — Vedanta).
