首楞嚴義疏注經 2.666

2.666

彼方，瓶來方也，名本瓶地。空若彼方來於此方，本瓶來處應少虛空；本處既無所少，應知非彼方來。瓶倒之地名為此方，若此方空入於瓶內，先合見空從瓶而出，方知空入。出空既無，入空何有？空既無出入，識何曾往來？又此方入者，入此方也。其文易解。

"That place" means the place where the bottle came from, called the location of the original bottle. If space came from that place to this place, the original place from which the bottle came should have less space; since there is nothing missing from the original place, one should know it did not come from that place. The ground where the bottle is overturned is called "this place"; if the space of this place entered inside the bottle, one ought to first see space emerging from the bottle before knowing that space entered. Since there is no exiting space, how could there be entering space? Since space has neither exiting nor entering, how could consciousness ever have going and coming? Furthermore, "entering at this place" means entering into this place. The text is easy to understand.
