An unshakable mind, and wisdom like a mirror
Ashuku Nyorai is the buddha of the Myōki world in the east, and his name means "unshaken" and "not angry." Among the Five Buddhas of the Kongōkai (Diamond Realm), he is placed in the east and represents the Great Perfect Mirror Wisdom (daienkyōchi), which reflects things just as they are.

A practitioner who vowed to cut off anger
In the story told in the Ashuku Bukkoku-kyō, a practitioner hears the Buddha's teaching and vows to cut off anger and desire and attain enlightenment. From this wish not to be moved by anger he came to be called Ashuku, and it is said that after becoming a buddha he continues to teach in the east.

Faith in the Pure Land of the east, and a buddha for memorial rites
Ashuku is revered as the buddha of a pure land in the east, and in esoteric Buddhism he is linked with the workings of wisdom. In the Japanese faith of the Thirteen Buddhas, he is assigned as the guide for the seventh-year memorial. Yakushi Nyorai is also a buddha of the east, but each has his own sutras and vows.

The view that links him with Yakushi Nyorai
Shōhōin's description of Ashuku Nyorai also introduces a view that he and Yakushi Nyorai are the same buddha. The relationship can be traced through what they share as buddhas of the east, but it is important to read Ashuku's Myōki world and Yakushi's Ruri-kō (Lapis Lazuli Light) world, as well as their sutras and vows, as distinct. This site does not treat one view as the shared position of all schools.
