Vaisnavism Saivism and Minar Religious Systems

The old Vedic gods became indissolubly involved in the elaborate and mechanical system of worship that had grown up. Speculations as regards the appropriateness of the rules and modes of worship, and their efficacy as regards man's good in this world and the next became prevalent. But all this did not satisfy the religious spirit of the people. Religious speculation of a more natural order came to be established about the close of the Hymn period and was continued into that of the Upanisads.
