妙法蓮華經文句 9.85

9.85

初入次入，乃至壞草庵通入中道，但入有漸頓故分二教。例入真諦，鈍者依析法、無常等觀，利者用體法空觀，故分藏通耳。

Initial entry, subsequent entry, and even demolishing the thatched hut to penetratively enter the Middle Way: it is merely that entry has the gradual and the sudden, hence two teachings are distinguished. By analogy with entering the ultimate truth: the dull rely on the contemplations of analysing phenomena, impermanence, and so forth, while the sharp use the contemplation of embodying the emptiness of phenomena; therefore the Tripiṭaka and shared teachings are distinguished.
