My dear lord, by your form as the Vedas personified and through knowledge relating to the activities of all the yajnic brahmanas, you spread the Vedic ritualistic ceremonies of the seven kinds of sacrifices, headed by agnistoma. Indeed, you inspire the yajnic brahmanas to perform the rituals mentioned in the three Vedas. Being the Supreme Soul, the Supersoul of all living entities, you are beginningless, endless and omniscient, beyond the limits of time and space.
The Vedic ritualistic ceremonies, the knowledge thereof, and the person who agrees to perform them are inspired by the Supreme Soul. As confirmed in Bhagavad-gita, mattah smrtir jnanam apohanam ca: [Bg. 15.15] from the Lord come remembrance, knowledge and forgetfulness. The Supersoul is situated in everyone’s heart (sarvasya caham hrdi sannivistah, isvarah sarva-bhutanam hrd-dese ’rjuna tisthati [Bg. 18.61]), and when one is advanced in Vedic knowledge, the Supersoul gives him directions. Acting as Supersoul, the Lord gives inspiration to a suitable person to perform the Vedic ritualistic ceremonies. In this connection, four classes of priests, known as rtvik, are required. They are mentioned as hota, adhvaryu, brahma and udgata.
