At the commencement of dissolution, the Lord appeared again in the form of horned fish. At the same time, Śeṣa, the Serpent King, appeared before the King Vaivasvata Manu in the shape of a rope, and the king, through his Yogic power, collected together all living beings and put them in the boat. And, after fastening the boat to the horn of the fish, by means of the rope, the king saluted the Lord and got into it.—17-19.
