Would doing regular Deep Subconscious Memory Resolution sessions targeting the lost souls in the holding place within the lower astral plane that is used to sequester and torment human spirits, be instrumental in allowing them to escape to the light?

Here again, is another brilliant insight, that a sticking point for these lost ones is that they are so far gone, and their own consciousness is limiting the possibility of rising above their dilemma. They truly are lost and believe they are doomed and cannot mount useful positive thoughts that could be a bridge to the light callers energetically. So this warrants an intervention, as you do for clients with your deep subconscious channeling, and the same happens with Creator-directed work on the deep subconscious of human beings to resolve trauma memories. Your request, as intentions coming from the human side, to specify a concerted effort to follow this DSMR protocol to work on the lost soul spirits being held in the holding place, is the key to their liberation. By the rules of engagement we cannot intervene unilaterally to rescue them. We can make attempts to entice, to invite, but if they do not respond, we cannot force anything further to happen. This protocol gives us the license to begin altering their frame of reference and find ways to raise their sights through applying healing restoration. That is exactly what is needed to get the job done and save these souls.
