摩訶止觀 2.121

2.121

後句者，即一切行惡之人，又不修止觀者是也。不修止觀，故不得道；根鈍，千遍為說，兀然不解。多造罪惡，遮障萬端，如癩人身痺，針刺徹骨，不知不覺；但以諸惡而自纏裹。

As for the last phrase, it refers to all those persons who commit evil deeds and also do not cultivate calming and contemplation. Because they do not cultivate calming and contemplation, they do not attain the Way; their faculties being dull, even if explained a thousand times, they remain completely benighted without understanding. Creating numerous offenses and evils, their obstacles and hindrances are manifold, like a leper whose body is numb, so that needles piercing to the bone leave him unaware and unfeeling; they merely wrap themselves in various unwholesome deeds.
