金剛般若波羅蜜經註解 1.189

1.189

又言算數譬喻所不能及者，蓋事相之福是可思議之法，而般若妙智忘能所、絕待對，不可得而思議者也。

Moreover, stating that "it is beyond what reckoning or metaphor can reach" is because the blessings of phenomenal marks are dharmas that can be conceived, whereas the marvelous wisdom of prajñā forgets subject and object, cuts off duality and relativity, and is inconceivable.
