Reading it as part of the history of sukuyō
Shōhōin explains that the Twelve Houses appear in the Sukuyō-kyō, the 七曜禳災訣 and other texts. They are placed within a history where astronomy and religion meet: reading the positions of the stars, making calendars, and performing prayers to remove misfortune.
