maghoni varsaty asakrd yamanuja
margam dadau sindhur iva sriyah pateh
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Because of constant rain sent by the demigod Indra, the river Yamuna was filled with deep water, foaming about with fiercely whirling waves. But as the great Indian Ocean had formerly given way to Lord Ramacandra by allowing Him to construct a bridge, the river Yamuna gave way to Vasudeva and allowed him to cross.
