The Vedas are a large body of texts originating in ancient India. Composed in Vedic Sanskrit, the texts constitute the oldest layer of Sanskrit literature and the oldest scriptures of Hinduism. Hindus consider the Vedas to be apauruṣeya They are supposed to have been directly revealed, and thus are called śruti distinguishing them from other religious texts, which are called smṛti In Hindu tradition, the creation of Vedas is credited to Brahma. The Vedic texts or śruti are organized around four canonical collections of metrical material known as Saṃhitās, of which the first three are related to the performance of yajna in historical Vedic religion:

The Rigveda, containing hymns to be recited by the hotar, or presiding priest;

The Yajurveda, containing formulas to be recited by the adhvaryu or officiating priest;

The Samaveda, containing formulas to be sung by the udgatar or priest that chants;

The Atharvaveda,a collection of spells and incantations,apotropaic & speculative hymns
