首楞嚴義疏注經 8.569

8.569

存想世間皆成變化，境既變化，心想亦亡，猶如槁木。有為功用暫得如是，故云絕行。如上十類皆云行者，日久成功通流故也。

Visualizing the world as all being transformation, once the realm is transformed, mental thoughts also perish, like dried wood. Conditioned effort temporarily attains this state; hence called transcendence-roaming. That all ten kinds above are called 'roaming' is because with time, their accomplished power flows through unobstructed.
