摩訶止觀 5.262

5.262

所以節節說見過者，殷勤行人，令於觀心善識毒草，明解藥王。若得此意，終不謬計也。章節雖煩，番番不雜。能了此者，可與論道；兀然如盲，若為識乳？

The reason for explaining the faults of views point by point is out of earnest concern for the practitioner, so that in contemplating the mind they will skillfully recognize poisonous grass and clearly understand the king of medicines. If they grasp this meaning, they will never fall into erroneous assumptions. Although the sections are intricate, stage by stage they are not confused. One who can comprehend this may be spoken with about the Path; if one is blank and inert like a blind person, how could they recognize milk?
