Diamond Realm

In Vajrayana Buddhism, the Diamond Realm (Skt. vajradhātu, Jp. 金剛界 kongōkai) is a metaphysical space inhabited by the Five Wisdom Buddhas.

The Diamond Realm is a very popular subject for mandalas, and along with the Womb Realm (Garbhakosa) Mandala forms the Mandala of the Two Realms.
