摩訶止觀 1.142

1.142

若爾，云何復言「遊心法界如虛空」？又言「無明、明者，即畢竟空」？此舉「空」為言端，空即不空，亦即非空非不空。又言「一微塵中有大千經卷」；「心中具一切佛法，如地種，如香丸」者，此舉「有」為言端。有即不有，亦即非有非不有。又言「一色一香無非中道」，此舉「中道」為言端。即中而邊，即非邊非不邊，具足無減。勿守語害圓、誣罔聖意。

If so, why is it also said: 'Roaming the mind in the dharmadhātu like empty space'? And why is it also said: 'Ignorance and clarity are both ultimate emptiness'? This takes 'emptiness' as the starting point of discourse, but emptiness is non-emptiness, and also neither empty nor non-empty. And why is it said: 'In a single speck of dust there is a great chiliocosm's roll of scripture,' and 'Within the mind all Buddha-dharmas are complete, like seeds in the earth or a pellet of incense'? This takes 'existence' as the starting point of discourse. Existence is non-existence, and also neither existent nor non-existent. And why is it said: 'A single color or a single fragrance is nothing other than the middle way'? This takes the 'middle way' as the starting point of discourse. Being identical to the middle, it is identical to the extremes; it is neither extreme nor non-extreme, complete without lack. Do not cling to words and damage the perfect, falsely slandering the holy intention.
