Bright Hall
An almanac describes traditional day-types. It cannot decide health, money, law, marriage or children. Burial, marriage and medical items on these pages are what a book states, never advice.
In the classical sources
房心為明堂天王布政之宫
The mansions 房 and 心 are the Bright Hall, the palace where the Heavenly King spreads his rule.

About this entry
Second in the list, 明堂 falls on the 丑 day in a 寅 or 申 month. 李鼎祚, quoted in 協紀辨方書 卷七, starts it at 丑 in the first month and moves it through the six yin branches, while the yang-branch spirits keep to a track of their own. Both 協紀 and 星厯考原 卷五 count it among the six 黃道 spirits.
曹震圭, also quoted there, pictures the hall where an emperor hears government business and supplies a second name, 執儲. The 1741 editors reject the trigram reasoning he builds on as absurd. They place the Bright Hall at 卯 through a line of 春秋說題辭 that identifies two mansions with such a hall.
