This is the first worship protocol foremost to all others (Pancharatham, etc.) which was begun for how to worship Lord Vishnu. This protocol has 8 divisions. Sri Vikhanasar has four disciples , namely "Athri", "Brughu", "Mareechi", "Kashyapar". One of the disciple started new protocols for saivam, etc. Those that belong to this Bhagavath Sastra are known to be part of Sri Vaikanasa archaka society. They are having privilege to worship and be the Priests at Temples just by their birth and no special sanctity or qualification is required for them to enter priesthood.
