Atharva Ved

Vedas are four books of sacred Hindu writing which are; the Rig-Veda, the Sama-Veda, the Atharva-Veda, and the Yajur-Veda. Vedas are important because they are a very high source of teachings.

It is the Rig Veda and not rgveda. In Hinduism, there are four such vedas, Rig Veda-the oldest, Sama veda, Atharva Veda and the Yajur Veda. These are considered to be sacred and they enlighten a human on how to lead a life peacefully and what salvation means.
