AtD translation: scaleless moments

[Mike Jing]

P515.14-19   He lapsed into silence, torpor, for scaleless moments seized
by memories of desert plateau, mountain peaks, meadows full of Indian
paintbrush and wild primrose, some unexpected river two steps off the
trail—then released back into this twenty-knot push into the uncreated. He
was not sure what it was he felt. If anyone had said desperation, he’d’ve
shrugged and rolled a cigarette, shaking his head. Not it. Not it exactly.

What does "scaleless" mean here?
