4.116

二十、示在四王。「各主二部鬼神」者，東主乾闥婆、毘舍闍，南主鳩槃茶、薜荔多，西主毒龍、富單那，北主夜叉、羅剎。「上一一事」下，總示上三十五事皆為扶成佛國，講說之者當知其宗。

Twenty, "Manifesting as the Four [Heavenly] Kings." Regarding "Each presiding over two classes of ghosts and spirits": the East presides over gandharvas and piśācas; the South presides over kumbhāṇḍas and pretas; the West presides over venomous nāgas and pūtanas; the North presides over yakṣas and rākṣasas. Below "Each of the above items," it shows in general that the thirty-five items above all serve to support and accomplish the Buddha-land; those who lecture and expound it should know its primary focus.
