Can the endoscopic thoracic surgery done for my client at age 17, be undone through healing across time? Or is it easier to heal the consequences expressed in his body directly?

This can be done even though it would seem surprising. In fact, many, many times the alleviation of symptoms through prayer for divine healing or the use of the Lightworker Healing Protocol accomplishes this very thing, to not attack the problem directly within the body systems and the kinds of dysregulation underway, but to go back in time and undo the proximal events leading to misalignment of things in the body, and this can include going across lifetimes to result in a restart of the current life with a differing genetic expression pattern that reduces vulnerability to an infirmity and this, in effect, uncreates the problem and the ongoing symptoms which will fade, apart from instances where cellular memory preserves them as a kind of memory and keeps them regenerated on autopilot, so to speak. So this is worth time and attention to request through prayer and LHP session work.
