俱舍論記 8.180

8.180

「此頌意顯至行無礙故」者，論主通經。造惡業已，速歸磨滅，無暫停義，故言中間無止。或據中有速往受生，故言中間無止。

Regarding the passage: "The intention of this verse is to show that... because movement is unobstructed": The author of the treatise clarifies the sūtra. Having committed evil karma, one quickly heads toward destruction without pausing, and for this reason it says there is no halting in between. Or, it refers to the intermediate state rapidly proceeding to take birth, and for this reason it says there is no halting in between.
