大般涅槃經集解 27.23

27.23

案僧亮曰：性重戒者，以犯四重，譬如拆石不可還合，退失聖照亦致世譏。但內障重故，從重受名也。譏謙戒亦如是也。僧宗曰：第四科，明乃至微細不犯也。寶亮曰：第三明或淺深也。夫有作罪者，運三毒而起也。豈有一罪而非性？若云俗人違法而無罪者，便是聖人為出家者作罪因緣。理豈然乎？此皆是性也。

Sengliang states: 'Inherently grave precepts' means that committing the four grave offenses is like splitting a stone, which cannot be rejoined; it brings loss of noble illumination and also causes worldly censure. But because the internal obstacle is grave, it is named after what is grave. The precepts against censure are also like this. Sengzong states: The fourth category clarifies that even the subtle [rules] are not violated. Baoliang states: The third clarifies the depth and shallowness of delusion. Whenever someone commits a sin, it arises from employing the three poisons. How could there be any sin that is not inherent? If one says that laypeople violating the Dharma are without sin, that would mean the sage creates the causes and conditions of sin for those who go forth. How could that principle be so? These are all inherent.
