Are the spirits of either his deceased wife or her mother attached to him, or in need of a Spirit Rescue?

The wife's mother's spirit did not return to the light on her passing but remained earthbound and she found her way to your client and his energy because he was a long-term caregiver and a point of focus for her consciousness when she passed. Not being ready or capable of interacting successfully with the light callers in returning to the heavenly realm, all she could think of was getting his help and missing her daughter. Both things made her vulnerable and led her to seek him out and his deep subconscious was sympathetic to her entreaties and this allowed her to gain entry as an attachment. The spirit does not realize she is in the son-in-law, so this adds to the difficulty of the situation. Your protocol work is just what is needed to do the healing required to bring some relief and allow a raising of the vibration of the spirit so it can cooperate with the light callers and be escorted to the light. this will allow him to begin a steady release of all the grief that has piled up within and will enable divine healing to achieve progress on his behalf so he can resolve this chapter in his life and begin to move on without suffering needlessly.
