The ancient Aryan religion was the Vedic religion that created the foundation for Hinduism. It was brought to India when the Aryans merged with the people of the Indus Valley.
The term "Aryan" comes from a Sanskrit word thought to mean "nobleman." The Aryans were a nomadic branch of the Indo-Europeans who wound up settling in what is now known as India. They believed in many gods, and they brought their Vedic religion with them, which lead to the birth of Hinduism when they met with the people of the Indus Valley. It is believed that the priests were socially superior. There are four Vedas: Rg Veda, which is the "Knowledge of Hymns of the Praise;" Sama Veda, which is the "Knowledge of the Melodies;" Yajur Veda, the "Knowledge of Sacrificial Formulas;" and Atharva Veda, the "Knowledge of Magical Formulas."
The different Vedas have different purposes, some are meant to be chanted, while others recited. Through the different Vedas, some gods are prayed to more than others, establishing their significance in the religion. Some of the most mentioned gods are Indra, Agni, Soma and Varuna. Indra was the god of storms, Agni was a messenger of the realms and Varuna was associated with knowledge. Soma was the divine equivalent of the soma plant, which Aryans used as a sacred intoxicant.
