大乘義章 7.7

7.7

次辨三業輕重之義。三業之中，何者最重？於中先以身口二業對彼意業以辨輕重，後別論之。言以身口對意辨者，意業最重，一切身口由意成故。又惡業中邪見最重，能斷善根，作一闡提。善業之中，三乘出道最為殊勝。世間之中，非想業勝。皆是心作，故知意重。次就三業別明輕重。身中最重，出佛身血。口中最重，所謂破僧、謗方等經。意中最重，所謂邪見惡業。如是善業之中，菩提之業最以為重。此三種中，身輕、口中、意為最重（此四門竟）。

Next, the meaning of the light and heavy among the three karmas is discriminated. Among the three karmas, which is the heaviest? In this, the two karmas of body and speech are first contrasted with mental karma to discriminate light and heavy, and afterwards they are discussed individually. As for contrasting body and speech with mind to discriminate them, mental karma is the heaviest, because all bodily and verbal [actions] are accomplished through mind. Furthermore, among unwholesome karmas, wrong view is the heaviest, for it can sever wholesome roots and make one an icchantika. Among wholesome karmas, the path of deliverance of the three vehicles is the most supreme. Among worldly [karmas], the karma of the [sphere of] neither-perception-nor-non-perception is superior. All these are made by mind; therefore, we know that mind is heavy. Next, light and heavy are explained individually according to the three karmas: Among bodily [actions], the heaviest is shedding the Buddha's blood. Among speech [actions], the heaviest is causing schism in the Saṃgha and slandering the vaipulya sūtras. Among mind [actions], the heaviest is wrong view. Such are unwholesome karmas; among wholesome karmas, the karma of bodhi is considered the heaviest. Among these three kinds, bodily is light, speech is medium, and mind is the heaviest.
