首楞嚴義疏注經 8.335

8.335

「情少想多，輕舉非遠，即為飛仙、大力鬼王、飛行夜叉、地行羅剎，遊於四天，所去無礙。」

"With little emotion and much thought, one flies upward, though not far, and becomes a flying immortal, a mighty ghost king, a flying yakṣa, or an earth-walking rākṣasa, roaming freely through the four heavens without obstruction wherever one goes."
