Each Veda consists of four parts--the Samhitas (hymns), the Brahmanas (rituals), the Aranyakas (theologies) and the Upanishads (philosophies). The collection of mantras or hymns is called the Samhita. The Brahmanas are ritualistic texts that include precepts and religious duties.
The name of its holy literature is The Vedas.
Hope it helps!
