The Mandala idea is good. Pick one that you both are drawn to. We will have to consider now how the medicines are prepared with regard to focussing on the patient also. It will do no harm to Initiate (D)’s parents and it is very kind of him to think this way.
When someone is Initiated it does set up a Connection with the Spiritual Realms which may or may not be explored. If this Connection is not explored then the person isn’t what we would call fully Initiated. The person needs to Meditate more to reach that point – when they reach Immersion into the Light and Sound. Only then can they begin their Spiritual Journey.
