etat payo-vratam nama
purusaradhanam param
pitamahenabhihitam
maya te samudahrtam
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
This is the religious ritualistic ceremony known as payo-vrata, by which one may worship the Supreme Personality of Godhead. I received this information from Brahma, my grandfather, and now I have described it to you in all details.
