金剛般若波羅蜜經註解 1.81

1.81

論云：「無住行施，因深也；無相見佛，果深也。因果之法既深，疑末世在迷鈍根眾生不如是能生信心。」

The treatise says: 'Practicing giving without abiding is profound in cause; seeing the Buddha through non-marks is profound in fruit. Since the dharmas of cause and fruit are profound, one doubts whether dull-rooted sentient beings mired in delusion in the final age will be able to produce faithful minds like this.'
