The Veda is believed to be of non-human origin, a container of timeless wisdom. Brahma sang these hymns out when he first saw Saraswati. These were transmitted to humans through seers known as Rishis. The seers who sat around Brahma heard four collections of Vedic mantras emerging from his four heads. These collections or samhitas came to be known as Rig, Sama, Yajur and Atharva. Of these Rig Samhita is believed to be the purest transmission.
