He also asks: “Is he in need of further LHPs for this particular problem.” What can we tell him?

It would be good to keep him on a wish list so further work you do, whether for him primarily or others, will still continue to support his learning and growth, and freedom from karmic difficulty. This is always a risk, that healing can be undone, and this is why your channel has set up the Divine Life Support program, because it quite specifically maintains ongoing support. First, to chip away at true causes of illness and other life dilemmas, and then to continue providing course corrections and a way to resolve unhealed trauma on an ongoing basis, as this can go a long way towards keeping people symptom-free, or at least from worsening of something that could become life-limiting as the deep healing continues.
