This is, I think, one of the reasons for self abusive behavior, whether through persistently bad decisions, irresponsibility, or outright self abuse, as through overeating, alcoholism, sexual addiction, drug abuse, or in extreme and literal cases, cutting and suicide attempts that are not serious: all of these, by bringing back pain, bring back a sense of presence. You are once again a participant in at least SOMETHING.
The hierarchy of spiritual development I have seen is relaxation, mindfulness, concentration. But I think anyone who has experienced trauma cannot even achieve the first properly, without preliminary work. What happens as you relax is the demons start to come out, you sense their advent, and pull back. You have to deal with them first.
Let us call this stage purification, until I change my mind. Preparation would also work. Right-sizing, head straightening, delunaticism, Sanification, blending, mixing (light and dark): I’ll have to smoke on this a bit. The best time might be the other side, which I think is approaching.
