大毘盧遮那成佛經疏 2.36

2.36

第六「云何智心！謂順修殊勝增上法」者，謂是人於種種所說中，皆以智簡擇此勝此劣、此應受此不應受、取其勝上者而後行之，即是無癡相也。然過人之法，非智力籌量所能及之，唯信者能入耳。是故觀察世智辯聰難，是彼對治。

Sixth: regarding "What is the mind of intellect? It means according with and cultivating superior and preeminent dharmas": this means that among diverse teachings, this person always selects with intellect what is superior and what is inferior, what should be accepted and what should not be accepted, taking the superior ones and only then putting them into practice; this is the mark of non-delusion. However, dharmas that transcend ordinary humans are not things that the power of intellect and deliberation can reach; only those with faith can enter. Therefore, contemplating [the defect of] the difficulty of worldly wisdom and cleverness of speech is its antidote.
