妙法蓮華經玄義 4.95

4.95

云何莊嚴名聖行？文云：「持佛淨戒」，佛戒即圓戒也。又云：「深達罪福相，遍照於十方」，即罪即福而見實相，乃名深達，以實相心離十惱亂等，皆是圓戒。「佛自住大乘，如其所得法，定慧力莊嚴」，即是佛之定慧莊嚴，故名佛聖行也。

How does adornment designate holy practice? The text says: 'Upholding the pure precepts of the Buddha'; the Buddha's precepts are the perfect precepts. It also says: 'Deeply penetrating the characteristics of sin and blessing, illuminating all ten directions'; seeing the real mark right within sin and blessing is called deep penetration, and using the mind of the real mark to be free from the ten kinds of vexations and so forth—these are all the perfect precepts. 'The Buddha himself abides in the Great Vehicle; according to the dharma he has attained, adorned with the power of concentration and wisdom'—this is the Buddha's adornment of concentration and wisdom, and is therefore called the Buddha's holy practice.
