From Chih-i’s scheme of the Ten Subtleties, we can clearly see that these Ten Subtleties are elaborated in an interrelated system. With this system, Chih-i offers us an extremely comprehensive scheme of Buddhism as a whole, with the ultimate goal of attaining Buddhahood. None of these categories of Subtlety can be looked at in isolation to others. Chih-i’s comprehensive system provides reconciliation to the two different tendencies in the South and in the North engaged in doctrinal discourse and practical approach respectively. With Chih-i’s system, the exclusive view of either emphasizing the doctrinal or the practical aspect of Buddhism is inadequate and irrelevant, because neither of these two aspects can exist without another; or rather, each aspect is elaborated in relation to the other.
