維摩經玄疏 1.68

1.68

答曰：此須得意。「為人」善厚惡輕，但不作眾惡，善自開發；「對治」惡厚善輕，故須眾善奉行，方得離惡也。

Answer: Here one must grasp the intent. In '[the siddhānta] for the person', goodness is profound and evil is slight; by merely not committing any evil, goodness naturally unfolds. In 'the therapeutic [siddhānta]', evil is heavy and goodness is slight; therefore, one must practice all goodness, and only then can one become free from evil.
