The Vedas are a collection of hymns and other ancient religious texts written in India between about 1500 and 1000 BCE. They are divided into four groups, Rigveda, Yajurveda, Samaveda, and Atharvaveda.
Rigveda: It is a collection of 1,028 Vedic Sanskrit hymns and 10,600 verses in all, organized into ten books.
Yajurveda: It consists of archaic prose mantras and also in part of verses borrowed from the Rig-Veda.
Samveda: It is the "Veda of chants" or "Knowledge of melodies". The name of this Veda is from the Sanskrit word saman which means a metrical hymn or song of praise.
Atharvaveda: It contains first-class poetry coming from visionary poets, much of it being a glorification of the curative powers of herbs and waters.
