Vaikhanasas claim to be a surviving school of Vedic ritual, the Taittiriya Shakha of the Krishna Yajurveda. Vaikhanasa tradition says the sage Vikhanasa, who was a manifestation of Lord Mahavishnu, had the Upanayanam along with Brahma consecrated by His father Lord Mahavishnu and educated under Lord Mahavishnu all the Vedas and Bhagawat Saastra on how to worship SriBhagawaan in His Archaavathaara - Iconic Form. Sri Vikhanasa Maharishi came down to earth's most holy place Naimisaaranyam composed the Vaikhanasa Kalpasutra and taught Sri Vaikhanasa Bhagawat Saastra to his four disciples viz., Atri, Bhrigu, Kashyapa and Marichi, respectively the procedures of Samurtarcana, Amurtarchana, devotional service to Vishnu in images. Most Vaikhanasa literature is almost completely concerned with rituals, prescribing the rituals and their rules of performance. To the Vaikhanasas their temple worship is a continuation of Vedic fire sacrifice. Regular and correct worship of Vishnu in a temple will bring the same results as the fire sacrifice even for people who do not maintain their fires.
