Furthermore, there are four great rivers that issue from Lake Anavatapta and flow toward the great ocean. The first is named Gaṅgā, the second is named Sindhu, the third is named Vakṣu, and the fourth is named Sītā. That Gaṅgā issues from the mouth of a golden elephant, circles the lake once, and flows toward the eastern ocean. That Sindhu issues from the mouth of a silver ox, circles the lake once, and flows toward the southern ocean. That Vakṣu issues from the mouth of a lapis lazuli horse, circles the lake once, and flows toward the western ocean. That Sītā issues from the mouth of a crystal lion, circles the lake once, and flows toward the northern ocean. Those four great rivers each have four rivers as their retinues—speaking only of the vast ones that have names. Yet those four rivers each have five hundred retinues, totaling two thousand rivers, which ultimately proceed to the great ocean (from the second fascicle of the *Vibhāṣā*).
