1.35

經。是故戒光至非無因故光　釋曰。第二歎德有三。一辨勝因。二光非青等下離相。三諸佛之本原下歎用。此即第一辨勝因。言戒光者。有其二義。一佛世尊常誦持故。欲說戒時有光明出。二所說戒能闍破故。假立光稱以戒能破破戒垢故。有緣者。謂此戒法三無數劫修習圓滿因所生故。非無因故。光者謂遮無因論。又有緣者。佛大慈悲本願因緣力有情感佛增上緣力。是故戒光從佛口出。如是光明必有因緣。非無因緣。而有此光。又欲說菩薩戒光因緣故。光非無因緣。

Sūtra: Therefore, the light of the precepts [from the mouth of the Buddha has causes and conditions] ... it is not that the light has no cause. Commentary: The second [part], praising the virtues, has three [points]: first, discerning the supreme causes; second, below, from 'the light is not blue, etc.', freedom from characteristics; third, below, from 'the source of all buddhas', praising the function. This is the first, discerning the supreme causes. As for 'the light of the precepts', there are two meanings: first, because the Buddha, the World-Honoured One, constantly recites and upholds them, when he wishes to expound the precepts, light emerges; second, because the expounded precepts are capable of shattering [afflictions], the name 'light' is conventionally established, since the precepts can shatter the defilements of breaking the precepts. 'Having conditions' means that this dharma of the precepts is born of the causes [of practice] cultivated and perfected over three incalculable eons; it is not without causes. 'Light' negates the theory of causelessness. Furthermore, 'having conditions' refers to the causal condition of the Buddha's great compassion and original vows, and the sovereign condition of sentient beings moving the Buddha. Therefore, the light of the precepts emerges from the Buddha's mouth. Such light necessarily has causes and conditions; it is not without causes and conditions that there is this light. Furthermore, because he wishes to expound the causes and conditions of the light of the bodhisattva precepts, the light is not without causes and conditions.
