首楞嚴義疏注經 1.236

1.236

境風外動，妄想內熏，識浪潛生為自心相。空華幻化，起滅無從，不了本如遂成久執。及推所在妄謂身中，反覆窮研理無所據，故佛結指令悟其非。

The wind of objective realms stirs outside, and delusion perfumes within; waves of consciousness stealthily arise, taken to be the mark of one's own mind. Like flowers in space and illusory transformations, their arising and ceasing have no origin; failing to understand their original suchness, one comes to cling to them for a long time. When investigating its location, one deludedly says it is in the body; examining and thoroughly researching it from every angle, the claim has no basis in reason. Therefore the Buddha draws the conclusion to instruct him, bringing him to realize his error.
