天台四教儀 1.57

1.57

三、說法品者，經云：「若有受持讀誦，為他人說。」內解轉勝，導利前人，化功歸己，心倍勝前。

3. The grade of explaining the Dharma. The sūtra states: 'If there are those who accept, uphold, read, and recite it, and explain it to others.' One's internal understanding becomes increasingly superior; in guiding and benefiting others, the merit of transformation returns to oneself, and the mind becomes doubly superior to before.
