Vajra Realm Mandala

Vajra Realm Mandala or Diamond Realm Mandala, is one of the two prominent mandalas in Chinese Esoteric Buddhism, as well as in the Shingon and Tendai traditions of Japanese Buddhism. The mandala is based on the Vajraśekhara Sūtra, one of the two fundamental scriptures in East Asian Esoteric Buddhism.
The teachings of Vajra Realm and Womb Realm are two major teachings of Chinese Esoteric Buddhism, as well as of the Shingon and Tendai traditions of Japanese Buddhism. Vajra Realm is associated with Transcendental Wisdom while Womb Realm is associated with Unconditional Compassion. Vajra Realm Mandala, together with Womb Realm Mandala, are called Mandala of the Two Realms.
The Vajra Realm Mandala is composed of nine Assemblies and is also known as Nine-Assembly Mandala. The top of the mandala corresponds to the west, while its bottom, left and right correspond to the east, south and north respectively, therefore the mandala is also called West Mandala.
