The Rig-Veda is a collection of over 1,000 hymns, which contain the mythology of the Hindu gods, and is considered to be one of the foundations of the Hindu religion. While the Rig is the oldest of the Vedas, there are three other Vedas. There is the Sama Veda, which is the “knowledge of chants” or a number of basic hymns recited at sacrifices. There is also the Yajur Veda or “knowledge of rites” which serve basically as a “how to make sacrifices” book. The final Veda is the Athara Veda, this Veda represents the knowledge given by Athara who was a sage. These Vedas were passed on or all.
