rgyal chen bzhi’i ris

One of the heavens of Buddhist cosmology, lowest among the six heavens of the desire realm (kāmadhātu, ’dod khams). Dwelling place of the Four Great Kings (caturmahārāja, rgyal chen bzhi), traditionally located on a terrace of Sumeru, just below the Heaven of the Thirty-Three. Each cardinal direction is ruled by one of the Four Great Kings and inhabited by a different class of nonhuman beings as their subjects: in the east, Dhṛtarāṣṭra rules the gandharvas; in the south, Virūḍhaka rules the kumbhāṇḍas; in the west, Virūpākṣa rules the nāgas; and in the north, Vaiśravaṇa rules the yakṣas.
