““Its meaning is to rest one-pointedly on the focal object [of meditation], without being distracted by other thoughts. If this [one-pointed resting] were stopped, all meditative concentrations would stop. Therefore, in general, "mental nonengagement" has the meaning of not mentally engaging in any object other than the very focus of the [respective] meditative concentration. In particular, when focusing on the ultimate, [mental nonengagement] has the meaning of letting [the mind] be without even apprehending this "ultimate." However, this should not be understood as being similar to having fallen asleep.””
