首楞嚴義疏注經 2.418

2.418

實相無相，即見無見，識劣智昧，無法空慧，如何通達？故勸善思不怠，大行可庶幾矣。

The true characteristic is without characteristics; seeing is without seeing. With inferior discernment and obscured wisdom, lacking the wisdom of the emptiness of phenomena, how could they penetrate it? Therefore he exhorts them to contemplate well without indolence, so that the great practice may perhaps be attained.
