首楞嚴義疏注經 6.101

6.101

「六者、聞熏精明，明遍法界，則諸幽暗性不能全，能令眾生藥叉、羅剎、鳩槃茶鬼及毘舍遮、富單那等雖近其傍，目不能視。」

"Sixth, hearing perfuming [the mind into] essential clarity, whose light pervades the dharmadhātu, so that all obscure darkness cannot retain its nature; this can cause sentient beings, though yakṣas, rākṣasas, kumbhāṇḍa ghosts, piśācas, pūtanas, and the like approach their side, to be unable to see them with their eyes."
