法苑珠林 24.31

24.31

又成實論云。若人但能為他說法。是名利他。是人雖不自隨法行。為他說故自亦得利。於此惠施門略有三品。下法施者。說布施法不說智慧。中法施者。說於持戒。上法施者。說於智慧。以說智慧。教人觀理得斷惑智二障出離生死遠成菩提涅槃樂果。乃至但能唯說小乘。教化一人令觀生空。信解依行雖未得道。亦勝教化一閻浮中所有眾生令行十善。以信解人解修聖道。則有出因要得涅槃。

Furthermore, the Tattvasiddhi-śāstra says: If a person is merely able to preach the Dharma for others, this is called benefiting others. Although this person may not practice in accord with the Dharma themselves, because they preach it for others, they also obtain benefit themselves. In this gateway of charitable giving, there are briefly three grades: the inferior giving of the Dharma is speaking the teaching of giving without speaking of wisdom; the middling giving of the Dharma is speaking of upholding the precepts; the superior giving of the Dharma is speaking of wisdom. Because by speaking of wisdom, one teaches people to contemplate the principle, attain the severing of the two hindrances of afflictions and knowables, escape saṃsāra, and ultimately achieve the blissful fruits of bodhi and nirvāṇa. Even if one is only able to preach the Hīnayāna, transforming a single person and causing them to contemplate the emptiness of the individual, so that having faithful understanding and relying upon it in practice, although they have not yet attained the Way, this still surpasses transforming all sentient beings in the entire Jambudvīpa and causing them to practice the ten wholesome deeds. Because once a person of faithful understanding understands how to cultivate the noble path, they possess the cause of deliverance and will inevitably attain nirvāṇa.
