In the Siddhānta-śiromaṇi, an astrological text, the different oceans are described as follows: (1) the ocean of salt water, (2) the ocean of milk, (3) the ocean of yogurt, (4) the ocean of clarified butter, (5) the ocean of sugarcane juice, (6) the ocean of liquor and (7) the ocean of sweet water. On the southern side of the ocean of salt water is the ocean of milk, where Lord Kṣīrodakaśāyī Viṣṇu resides. He is worshiped there by demigods like Brahmā.
