問曰。云何佛道至尊至快無為憺怕。世人學士多謗毀之云。其辭說廓落難用。虛無難信何乎。

The questioner said: "Why is it that, although the Buddhist Dao is supremely revered, supremely pleasant, and consists of non-action and tranquil calmness, the worldly scholars mostly slander and revile it, saying that its expressions are vast and empty, difficult to apply, vacuous and difficult to believe? Why is that?"
