首楞嚴義疏注經 1.345

1.345

挃（陟栗切），猶觸也。以手觸身，必先知覺。既言有體，不無所止，內外二處必從一緣，故今雙詰。難同前破。

"Poke" (zhi, fanqie: zhi + li) is like touching. Touching the body with a hand, there must first be awareness. Since you say it has substance, it cannot be without a location; the two locations of inside and outside must derive from one of the conditions, which is why he now interrogates both. The difficulty is the same as the earlier refutation.
