菩薩戒義疏 2.32

2.32

第十六、為利倒說戒，乖訓授之道故制。七眾同犯，大小乘俱制。前戒隱大示小，今戒雖為說大，而希利靳固，隱沒義味不令顯示。聲聞教訓他人，隱沒義理犯輕垢。序事三階：一、先應自學，二、為後來者具說，三、明不應為利隱沒。就文易見。有師言：此中所列苦行制令救物，不爾輕垢。又解：是舉沒況之辭。大士當應捨身施人，然後具為說法，況今止為說法而希利隱沒耶？後階示三，文相易見。

Sixteenth: The precept against preaching upside-down for the sake of gain. It is instituted because it contradicts the way of instructing and teaching. All seven assemblies share in the transgression; it is instituted commonly for both the Mahāyāna and the Hīnayāna. The previous precept concealed the Great and displayed the Small; this precept, although one preaches the Great, entails that desiring gain and grasping tightly, one conceals the flavor of the meaning and does not allow it to be revealed. When a śrāvaka instructs others, concealing the meaning and principles incurs a minor defilement infraction. The narration of matters has three stages: first, one must first study oneself; second, one must preach fully for later comers; third, explaining that one should not conceal it for the sake of gain. This is easily seen from the text. A certain master says: The ascetic practices listed here are prescribed to cause one to save beings; otherwise it is a minor defilement. Another explanation is: These are words of bringing up what is extreme to illustrate [the lesser]. A mahāsattva should renounce his body and give it to others, and thereafter preach the Dharma fully for them; how much less now, merely preaching the Dharma, should he desire gain and conceal it? The latter stage shows three [points], the textual aspects of which are easily seen.
