摩訶止觀 3.85

3.85

2. Explaining the eyes and wisdoms: the substance is neither knowing nor seeing, neither cause nor fruit; speaking of it is already difficult in itself, so how much more so showing it to others? Although it cannot be known or seen, through the eyes and wisdoms it can be known and seen; although it is not cause or fruit, it is revealed through cause and fruit. Calming and contemplation are the cause; wisdom and the eyes are the fruit. The cause is the remote origin that reveals the substance; the fruit is the proximate origin that reveals the substance. Its substance is profound and wondrous, beyond distinction; we rely on the eyes and wisdoms so that the substance can be understood.
