法苑珠林 48.12

48.12

所以然者。諸惡莫作。戒具之禁清白之行。諸善奉行。心意清淨。自淨其意。除邪顛倒。是諸佛教。去愚惑想。云何迦葉。戒清淨者。意豈不淨乎。清淨者。則不顛倒。以無顛倒愚惑想滅。諸三十七道品果便得成就。以成道果。豈非諸法乎。

Why is this so? 'Do not commit any evil' refers to the full precepts and clean, pure conduct. 'Cultivate all good' refers to the purification of the mind. 'Purify one's own mind' refers to removing false inversion. 'This is the teaching of all Buddhas' refers to banishing thoughts of delusion and confusion. How so, Kāśyapa? If the precepts are pure, how could the mind not be pure? When pure, there is no inversion; through the absence of inversion, thoughts of delusion and confusion are extinguished. The fruits of the thirty-seven factors of awakening are then realized. Having realized the fruits of the Path, are these not all the teachings?
