維摩經略疏垂裕記 5.112

5.112

問曰：亦有一智而緣多境，如以俗智照具照中及以真俗更互轉照，其理何耶？答：若論通相入空境智，即以一俗對於三真，互照轉照非此所論。

Question: There is also one wisdom taking multiple objects as conditions, as when conventional wisdom illuminates both completeness and the middle, and true and conventional mutually illuminate each other in turn; what is the principle behind this? Answer: If one speaks of the object and wisdom of entering emptiness in its common aspect, then one opposes one conventional [wisdom] to the three truths; mutual illumination and illumination in turn are not what is discussed here.
