Was my client’s subconscious channeling session focused on the best experiences to help his current happiness, and uncontaminated from mistakes or misinterpretations on my part?

This is very much the case. You did a superb job in seeing what was coming through and following closely and accurately the channeled information without interposing your own thoughts or seeking information through intention that could distort things. Your disquiet was solely because knowing so little about him and his issues, it was not easy for you to follow the thread here and understand how these events might have a very big impact on things and be relevant to his current dilemmas, but we can assure you it is very much the case and this session will be of great service.
