The Nine Luminaries: celestial bodies represented as deities
The Nine Luminaries are the seven luminaries (the sun, the moon, Mercury, Venus, Mars, Jupiter and Saturn) plus Rago and Keito. Rago and Keito are concepts related to the points where the apparent paths of the moon and the sun cross; they are not two planets visible to the naked eye. Here, images representing celestial bodies as Buddhist deities are introduced.

Prayers at the star festival to remove misfortune and invite good fortune
Shōhōin explains the star festival (hoshi matsuri) as a Buddhist service that enshrines the Nine Luminaries and the Twenty-Eight Lunar Mansions and prays for removing misfortune and inviting good fortune. The grouping of the Nine Luminaries combines knowledge that grasps the movements of the heavens with the wish to spend each day peacefully.
