My client’s son has been diagnosed with bipolar disorder in the past, and has struggled most of his life. Would he benefit from subconscious channeling?

This would be excellent for him. He has had many spirit influences during his upbringing but his primary issues are karmic as is true of most people. There is an interplay, as you know, because the dark spirits use the karmic vulnerabilities to bully their host and cause inner conflict so this would help him restore himself from the ravages of their campaign of belittlement and torment.
