Cause-and-effect are temporal manifestations: intemporally they are one. Temporally, volition is a causal factor (an immediate cause), itself an effect.
When the informing Mind (the unnameable - because non-objective - factor which informs all appearance) shines through the mist which results from identification with a phenomenal object, volition becomes illusory, since it is of the texture of that mist.
Cause-and-effect continue to operate, but volition as a causal factor is eliminated. A body is still lived by causation, but the phenomenal aspect of mind, the split (dualistic) aspect of subject-and-object, is freed from all that depended on volition, affective or intellectual, and is thereby liberated.
