In the ancient Neolithic age, when the human civilization started settling as groups in small villages, as farmers, hunters and traders, people started recognizing the social need for prayers to a supreme being and various forms of theology and philosophy evolved. Each of the communities had their own form and system for worship and religious practice. Most groups prayed for various forms of natural forces. Many social leaders and kings were elevated to the levels of a God and people worshipped their images. While nomadic communities mingled together through travel and war, many different forms of worship coexisted. Many primitive people and later civilizations like the Greeks, Romans, Egyptians and Persians had multiple forms of worship of God. They had many gods, one for each form of force or activity. Reformed religious movements in the ancient times like the Judeo-Christian and Zoroastrian religions denied and opposed the practice of polytheism. Their Messiah had a spiritual experience and true revelation of the Divine. They opposed and eliminated all old beliefs and established their own faith of "One God."

Vedic forms of Hindu religion, where every one was allowed to have the spiritual experience and true revelation of the Divine, came across the nomadic and farming communities in villages who were worshipping the different forms of "Gods." They accepted all those variations in faith and worship rituals. They showed tolerance and believed that there are many paths to One Supreme Reality. The Agamas explained the several forms like Siva, Vishnu, Vasudeva, Muruga and Kali as manifestations of the Supreme Formless God. Vedas also explained the Vedic Deities of natural forces like Varuna and Agni as many subordinate forces working under the Divine command of the Supreme Brahmam. Thus Hindus accept in one supreme God who is without form and has no attributes. He takes the various forms so that the people can comprehend His Glory.
