四教義 10.21

10.21

次雷音三昧破三禪有者，此禪受樂最為第一，著樂深入如氷魚蟄蟲，菩薩為破此樂，故用三諦雷音以驚駭，推之可解。

Next, the thunder-sound samādhi destroys existence in the third dhyāna. The experiencing of pleasure in this dhyāna is foremost; being deeply attached to pleasure, they are like fish in ice or hibernating insects. In order to destroy this pleasure, the bodhisattva uses the thunderous sound of the three truths to startle them. By deduction it can be understood.
