首楞嚴義疏注經 1.637

1.637

「世尊！譬如行客，投寄旅亭，或宿或食。宿食事畢，俶裝前途，不遑安住。若實主人，自無攸往。如是思惟，不住名客，住名主人，以不住者名為客義。」

"World-Honoured One! For example, a traveling guest stops at an inn, either lodging or eating. Having finished lodging and eating, he packs his bags and takes to the road, having no leisure to remain peacefully. If he were truly the host, he would naturally have nowhere to go. Contemplating like this: not staying is called 'guest', and staying is called 'host'; thus, not staying is the meaning of 'guest.'"
