金剛般若波羅蜜經註解 1.95

1.95

言筏喻者，論云：「如欲濟川，先應取筏，至彼岸已，捨之而去。」又，《智論》引《筏喻經》云：「汝等若解我筏喻法，是時善法宜應棄捨，況不善法？」斯乃無所得之要術，俾不凝滯於物矣。

Regarding the raft parable, the treatise says: 'Just as when one wishes to cross a river, one should first take a raft, and having reached the other shore, abandon it and go on.' Furthermore, the Mahāprajñāpāramitopadeśa quotes the Raft Parable Sūtra, saying: 'If you understand my raft parable teaching, at that time even wholesome dharmas should be discarded, how much more so unwholesome dharmas?' This is the essential method of having nothing to attain, ensuring that one does not become fixated on things.
