11. The Agamas-1
1.The Vaishnava Agamas
The Vaishnava Agamas are of four kinds: the Vaikhanasa, Pancharatra, Pratishthasara and Vijnanalalita. The Brahma, Saiva Kaumara, Vasishtha, Kapila, Gautamiya and the Naradiya are the seven groups of the Pancharatras. The Naradiya section of the Santi-Parva of the Mahabharata is the earliest source of information about the Pancharatras.
Vishnu is the Supreme Lord in the Pancharatra Agamas. The Vaishnavas regard the Pancharatra Agamas to be the most authoritative. They believe that these Agamas were revealed by Lord Vishnu Himself. Narada-Pancharatra says: “Everything from Brahma to a blade of grass is Lord Krishna.” This corresponds to the Upanishadic declaration: “All this is, verily, Brahman—Sarvam Khalvidam Brahma.”
There are two hundred and fifteen of these Vaishnava texts. Isvara, Ahirbudhnya, Paushkara, Parama, Sattvata, Brihad-Brahma and Jnanamritasara Samhitas are the important ones.
