妙法蓮華經玄義 1.145

1.145

私十五番釋其相令易解：隨說事理，聞者適悅是世界；舊善心生是為人；新惡除遣是對治；得悟聖道是第一義。

Privately, I provide fifteen rounds of explanation of their characteristics to make them easy to understand: Whichever principle or phenomenon is preached, if the hearer is pleased and delighted, it is the worldly [siddhānta]; if an old wholesome mind arises, it is [the siddhānta] for individuals; if new evil is eliminated, it is the therapeutic [siddhānta]; if one awakens to the noble path, it is the supreme-truth [siddhānta].
