Many feel temporarily free of ego-mind's grip, experiencing a new state of being, of awareness. But, in due time, it's back to business as usual.
Call it the rubber band effect, a snapping back into one's conditioned mind. Why? Because ego-mind's operating system was somehow put into hibernation or sleep mode, allowing a shift of usual awareness, but then was reactivated.
Disconcerting to say the least.
Not only that, but potentially problematic.
Interference on the re-entry that promotes delusion? One error is feeling liberated, attaining a spiritual state that one isn't really prepared for. Unfortunately, one is no less bound in most cases.
By prepared you mean a process of purification.
Purification in the sense of effacement, of the dismantling of who we think we are.
