摩訶止觀 3.133

3.133

一、智者，經云：「一切諸如來，同共一法身；一心一智慧，力無畏亦然。」唯一佛智即一切種智，一相寂滅相；種種行類、相貌皆知，名「一切種智」。此智觀三諦者，若言「一相寂滅相」，即是觀於中道；若言「種種行類、相貌皆知」者，即是雙照二諦也。

First, one wisdom: a sutra states, 'All Tathāgatas share the same single dharmakāya; one mind and one wisdom, and likewise with the powers and fearlessnesses.' There is only one Buddha-wisdom, which is sarvākārajñatā, a single characteristic that is the characteristic of quiescence; knowing all kinds of categories of action and appearances is called 'sarvākārajñatā'. When this wisdom contemplates the three truths: to say 'a single characteristic that is the characteristic of quiescence' is to contemplate the middle way; to say 'knowing all kinds of categories of action and appearances' is to illuminate both [other] truths.
