Would a channeling of this autistic child’s Higher Self be useful to understand his situation or would a channeling with his deep subconscious, or conscious self, help the most in understanding his dilemma?

Understanding his dilemma and healing it are not the same. When there is a financial and time constraint, we would favor devoting available resources to healing rather than simple information gathering. In this case, the autism was due to external manipulation. He is a victim of the Ibis program and this is his current dilemma, that he has been altered. This increases the ability of divine realm to undo things because it is not entirely a consequence of the client’s personal choices leading to the dilemma. One of the consequences, however, of being in his current state is the long-term suffering and experiencing of having such limited ability to communicate with the outside world. So his mind and body both, are filled with many experiences of trauma, including what is happening behind the scenes with his spirit meddler attackers. To root this out would be best accomplished through subconscious channeling and guided imagery with Holographic Memory Resolution. This is a perfect answer for the entirety of his problems, from the autism to the trauma arising as a consequence of the autism, and would be a grand undertaking. This will not be quick in coming, because multiple sessions would be required. But it is always good to know the possibility is there, and then planning and decisions can be made depending on availability of time and the financial support. As we know, this resource from you is quite limited and you are currently overburdened as it is.
