大般涅槃經義記 10.88

10.88

下第八番破指住處以為虛空。與前第二物住之處名為虛空大況相似，破法不同故須更論。「若有說言指住之處名為虛空」舉他所立。「當知」已下徵令無常。「何以」下釋。於中初明指住之處名為空故，隨指有方。「一切常」下，明有方所必是無常。於中，先明常法無方。「以有方」下，明有方故必是無常。「若無常」下，明是無常，不離五陰。「要離」已下，明非五陰，是無非有。

Below, the eighth section refutes taking the place where a finger abides to be space. It is largely similar to the earlier second [section where] the place where objects abide is called space, but because the method of refutation differs, it must be discussed again. 'If someone says that the place where a finger abides is called space' cites the opponent's position. From 'One should know...' downward, it challenges it to be impermanent. From 'Why is this?' downward, it explains. In this, it first clarifies that because the place where a finger abides is called space, it has direction following the finger. From 'All permanent...' downward, it clarifies that having a spatial location necessarily implies impermanence. In this, it first clarifies that permanent dharmas have no direction. From 'Because it has direction' downward, it clarifies that because it has direction, it is necessarily impermanent. From 'If it is impermanent' downward, it clarifies that if it is impermanent, it is not apart from the five aggregates. From 'It must be apart...' downward, it clarifies that it is not the five aggregates, and is non-existent, not existent.
