又是七種二諦智行：圓真方便即是聖行；圓真之理即是天行；悲七俗、慈七善即梵行；同七俗即病行；同七真即嬰兒行。

Furthermore, they are the practice of wisdom regarding the seven kinds of two truths: the expedients of the perfect real [truth] are the holy practice; the principle of the perfect real [truth] is heavenly practice; compassion for the seven kinds of conventional [truth] and benevolence toward the seven kinds of good are pure practice; identifying with the seven kinds of conventional [truth] is practice regarding illness; identifying with the seven kinds of real [truth] is practice regarding infants.
