《灵枢·九宫八风》“太一游宫”的两个问题

Two Problems about Taiyi’s Tour in the Nine Palaces and Eight Winds Chapter in the Efficacious Pivot

《九宫八风》的“太一岁游”和“太一日游”是两种性质不同的太一游宫形式,前者侧重于天文历法观念,后者带有明显的数术化特征,但前者是后者的前提,不能认为“太一岁游”的“大周期”是由“太一日游”的“小周期”构成。《九宫八风》据太一游宫之理言及三种占法,即“太一移日占”“五宫贵贱占”以及“中宫八风占”,前两种占法可配合汝阴侯墓出土的太乙九宫占盘得到说明,“中宫八风占”则由《九宫八风》的作者转化为理性化的医学观念,其与兵阴阳的风占术亦存在明显的不同。

The“one-year tour of Taiyi(Great One)”and the“one-day tour of Taiyi”in the Nine Palaces and Eight Winds chapter are two different forms of Taiyi’s tour in palaces.The former focuses on astronomical and calendrical concepts,while the latter has obvious features of the art of calculation.However,the former is the premise of the latter.It cannot be considered that the“big cycle”of the“one-year tour of Taiyi”is composed by the“small cycles”of the“one-day tour of Taiyi”.According to the theory of Taiyi’s tour in palaces,the chapter of the Nine Palaces and Eight Winds mentioned three kinds of method of divination,namely,“Taiyi yiri(the movement of the Great One in different days)divination”,“high-rank and low-rank five palaces divination”and“the central palace and eight winds divination”.The first two methods can be explained with the“divinatory board of the Great One with nine palaces”unearthed from Marquis Ruyin’s tomb.The“central palace and eight-wind divination”was transformed by the author of the Nine Palaces and Eight Winds into a rational medical concept,which is also obviously different from the military yin-yang school’s divination by wind.
