Tracing the figure and traditions
It is said that this is to cut off delusion and desire and make people awaken to impermanence, and it is handed down that when he grows angry, demonic hindrances appear and the land falls into disorder.

Deities who guard the directions, heaven and earth, and the sun and moon
The Twelve Ten are protective deities connected with the eight directions — north, south, east, west and the four corners — above and below, the sun and the moon. They combine Taishakuten, Katen, Enmaten, Rasetsuten, Suiten, Fūten, Tamonten and Ishana-ten with Bonten, Jiten, Nitten and Gatten. It is a grouping that welcomes the deities who protect nature and space into Buddhist ritual.

Prayers that guard the place of ritual and remove disaster
Shōhōin links the Twelve Ten with prayers for harmony with nature and for warding off disaster, and describes them as beings who guard the place of the denpō kanjō (transmission consecration). The direction and held objects of each deity belong to this system of protection. It is a grouping separate from classifications of Shinto kami and from the twelve signs of the Western zodiac.
