答：「辨其難易故且揀之，若論機入不同故須雙列，復為顯其妙義必須內外互融，隨觀一境皆能遍攝故名不二，此之不二悉得稱門。泛論雖爾，一家觀法多用內心妙義為門也。」

Answer: "They were set aside temporarily in order to distinguish ease and difficulty. But if we discuss the differences in capacities and entrances, both must be listed. Furthermore, to reveal their wondrous meaning, the internal and external must mutually fuse; following contemplation of either single object, both are fully capable of pervading and subsuming [all], hence it is called 'nondual', and all such nondualities are termed 'gates'. Although this is so in general discussion, the contemplation methods of our school mostly use the wondrous meaning of the internal mind as the gate."
