Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Sri Sukadeva Gosvami continued: Thus one should worship Lord Visnu, who is known as Srinivasa, along with mother Laksmi, the goddess of fortune, by offering prayers according to the process mentioned above. After removing all the paraphernalia of worship, one should offer them water to wash their hands and mouths, and then one should worship them again.
