The Vedas are the large bodies of religious text that is composed of Vedic Sanskrit and originated in ancient India. They form the oldest scriptures of Hinduism and the oldest layer of Sanskrit literature. The Vedas are said to have passed on through verbal transmission from one generation to the next. Therefore, they are also known as Shruti. The Vedic literature consists of four Vedas, namely: Rig Veda, Sama Veda, Yajur Veda, and Atharva Veda. The mantra text of each of the Vedas is called Samhita.
