“While Vasudeva was carrying his son Krishna in the falling rain, Lord Shesha in the shape of a serpent spread His hood over the head of Vasudeva so that he would not be hampered by the rainfall. Vasudeva came onto the bank of the Yamuna and saw that the water of the Yamuna was roaring with waves and that the whole span was full of foam. Still, in that furious feature, the river gave passage to Vasudeva to cross, just as the great Indian Ocean gave a path to Lord Rama when He was bridging over the gulf.” (Krishna, The Supreme Personality of Godhead, Vol 1, Ch 3)
