PURPORT

In the Siddhanta-siromani, an astrological text, the different oceans are described as follows: (1) the ocean of salt, (2) the ocean of milk, (3) the ocean of curd, (4) the ocean of clarified butter, (5) the ocean of sugar cane juice, (6) the ocean of liquor and (7) the ocean of sweet water. On the southern side of the ocean of salt is the ocean of milk, where Lord Ksirodakasayi Visnu resides. He is worshiped there by demigods like Brahma.
