首楞嚴義疏注經 5.114

5.114

中道正觀如幻三昧，能解無始無明根結，能於彈指超證無學，能起無方不思議用，此名佛法從因緣生，豈同世間所說麁相。以佛無明永盡，得一切種智，故能知此結解因由，非餘境界。

The correct contemplation of the Middle Way is the vajra-king illusion-like samādhi: it can untie the beginningless knotted root of avidyā, it can transcend and realize the stage of non-learning in the snap of a finger, and it can bring forth boundless, inconceivable functioning. This is what is called the Buddha-Dharma arising from causes and conditions; how could it be the same as the coarse characteristics spoken of by the world? Because the Buddha's avidyā is forever exhausted and he has attained the knowledge of all aspects, he is able to know the reasons for these knots and their untying, which is not the realm of anyone else.
