維摩經略疏 7.65

7.65

「如佛至是處」，三、引佛語證釋正觀義。義既深邃，淺行未達，各生疑網，是故引證。

From "As the Buddha [said...] down to this place," third, cites the Buddha's words to verify and explain the meaning of the correct contemplation. Because the meaning is profound and those of shallow practice have not attained it, each giving rise to a net of doubt, proof is therefore cited.
