 Zhiyan intends for the ten mysteries to apply to ten categories of dharmas. He presents each category as a pairing among contraries: doctrine and meaning, li and shi, understanding and practice, cause and result, person and dharma, realms and stages, teacher and disciple, chief and attendants, substance and function, response and stimulus. But there is no apparent pattern or system to the order in which Zhiyan presents the ten mysteries, nor does Zhiyan explain how each category applies to each mystery.
