摩訶止觀 7.12

7.12

次、用橫織竪檢校中道正觀者：於無明、法性、真緣等，一一法、一一能、一一所，明識諦、緣、度。若起三塞，破之令通；若有三通，養令成就。則過無明之塞，通五百由旬。

Next, using the horizontal woven into the vertical to examine the correct contemplation of the middle way: regarding avidyā, dharmatā, the true and the conditioned, and so forth—in each and every dharma, each and every subjective capacity, and each and every objective realm—clearly discern the truths, the links [of conditioned arising], and the perfections. If the three obstructions arise, break them to make them open; if there are the three openings, nurture them to bring them to completion. Then one surpasses the obstruction of avidyā and opens the five hundred yojanas.
