摩訶止觀 6.84

6.84

但凡情闇鈍，不說不知，先誘開之，後入正道。《法華》云：「雖說種種道，其實為一乘。」若得此意，終日分別，無所分別。《涅槃》名為「復有一行是如來行。」《法華》名「正直捨方便，但說無上道。」《大品》名為「一切種智知一切法。」《淨名》稱為「入薝蔔林，不嗅餘香。」《華嚴》稱為「法界」。即是此四門意也。

It is merely that ordinary sentiments are dull and obscured; without explanation they do not understand. First one entices and opens them up, and later they enter the correct path. The Lotus [Sūtra] says: 'Although various paths are spoken of, in truth they are for the One Vehicle.' If one grasps this meaning, though making distinctions all day, there is nothing distinguished. The Nirvāṇa [Sūtra] calls it: 'There is yet another practice, which is the practice of the Tathāgata.' The Lotus [Sūtra] calls it: 'Honestly discarding expedients, only expounding the unsurpassed path.' The Large [Prajñāpāramitā] calls it: 'Sarvākārajñatā knows all dharmas.' The Vimalakīrti calls it: 'Entering the campaka grove, one does not smell other scents.' The Avataṃsaka calls it 'the dharmadhātu.' Such is the intention of these four gates.
