Is there anything further he can do to help his healing?

His role in this is one of self-love and self-acceptance, to not blame but to focus on the spiritual goal of his life and the benefits of his work, for they are a contribution and they will actually help with his healing as well as stir the pot, so to speak. So we do not want to leave the impression he must end his career. That would help his healing, but is not essential for healing to happen. And, in fact, there is some healing benefit because the extent to which he is contributing to seeking the truth, helping to awaken others, and stimulate discussion and consideration of new ways of seeing and solving the problems of society, those benefits will add to the ledger in the plus column, so to speak, and will help give the fuel to restoration and resolving the karmic burdens he may still carry.
