菩薩戒義疏 2.31

2.31

第十五、僻教戒，使人失正道故制。七眾同犯，大小乘不共，以所習異故。序事三階：一舉所應教人，「自佛弟子」謂內眾，「外道」謂外眾，「六親、善知識」通內外。二、明應，應教大乘經律令發菩提心。十心者，十發趣心起，金剛心謂十金剛，略不說十長養。此三十是始行者急須，應為開示故。三、明不應，不應惡心教二乘外典等。若見機益物，不犯。

Fifteenth, the precept against deviant teaching: it is established because it causes people to lose the right path. All seven assemblies commit the offense alike; the Mahāyāna and Hīnayāna do not share it, because what they practice is different. The narration of matters has three stages: first, adducing the persons who should be taught: "one's own disciples of the Buddha" refers to the internal assembly; "non-Buddhists" refers to external assemblies; "six kinds of relatives and good spiritual friends" applies to both internal and external. Second, explaining what is proper: one should teach the Mahāyāna sūtras and vinaya, causing them to arouse the bodhicitta. The "ten minds" means the arousal of the ten minds of aspiration; the "vajra minds" refers to the ten vajra [minds], while the ten nourishing [minds] are omitted in this brief account. These thirty are what beginners urgently need, so one should disclose them to them. Third, explaining what is not proper: one should not, with an evil mind, teach the two vehicles, non-Buddhist scriptures, and the like. If one sees an occasion to benefit beings, there is no offense.
