摩訶止觀 2.114

2.114

云何一人？若人欲聞四種三昧，聞之歡喜，須遍為說，是為世界。以聞四種，次第修行能生善法，即具說四，是各各為人。或宜常坐中治其諸惡，乃至隨自意中治其諸惡，是名對治。是人具須四法，豁然得悟，是第一義。秖為一人尚須四說，云何不用耶？若為多人者，一人樂常坐，三非所欲；一人欲常行，三非所樂。遍赴眾人之欲，即世界悉檀也。餘三悉檀亦如是。

What is meant by for a single person? If a person wishes to hear about the four kinds of samādhi and rejoices upon hearing them, one must explain them comprehensively; this is the mundane [siddhānta]. If, upon hearing the four, practicing them in sequence can generate wholesome dharmas, one explains all four completely; this is the individual [siddhānta]. If it is suitable to cure their unwholesome states in the constantly sitting [samādhi], up to curing their unwholesome states in 'following one's own thought,' this is called the remedial [siddhānta]. If this person, fully requiring the four practices, suddenly attains awakening, this is the supreme truth [siddhānta]. If even for one person four expositions are still needed, why should they not be used? As for being for many people: one person delights in constant sitting, the other three not being what is desired; another person wishes for constant walking, the other three not being what is preferred. Pervasively meeting the desires of many people is the mundane siddhānta. The remaining three siddhāntas are likewise.
