摩訶止觀 2.85

2.85

凡夫若縱惡蔽，摧折俯墜，永無出期，當於惡中而修觀慧。如佛世時，在家之人帶妻挾子，官方俗務，皆能得道。央掘摩羅彌殺彌慈；祇陀末利唯酒唯戒；和須蜜多婬而梵行；提婆達多邪見即正。若諸惡中一向是惡，不得修道者，如此諸人永作凡夫。以惡中有道故，雖行眾蔽，而得成聖，故知惡不妨道。

If ordinary people indulge in evil hindrances, break down, and fall downwards, they will have no time of escape; they should practice contemplative wisdom right within evil. For example, during the Buddha's lifetime, laypeople who had wives and children and engaged in official duties and worldly affairs were all able to attain the Way. Aṅgulimāla killed ever more yet became ever more compassionate; Jeta and Mallikā were absorbed only in wine and precepts respectively; Vasumitrā indulged in lust yet engaged in pure conduct; Devadatta had wrong views, which were themselves right. If within various evils it were exclusively evil and one could not cultivate the Way, people such as these would eternally remain ordinary mortals. Because the Way exists within evil, although they enacted manifold hindrances, they were able to become sages; hence one knows that evil does not obstruct the Way.
