Healing techniques and non-duality: listener question

You refer toparentimng the child.  For years,  I have used inner child healing  in hypnotherapy with my clients. I also use parts therapy to facilitate understanding, acceptance and integration of problem behaviours (parts)  into the whole, Havening to offer comfort and reassure as difficult or traumatic situations are considered, EMDR to release unprocessed trauma, EFT and matrix reimprinting and mindfulness to turn towards the sensations and thoughts that create difficulty from a place of observation. Are these all legitimate healing methods and how does their emphasis change if used in a non-dual context? I can see without guidance how easy it would be to revert to the old conditioned appearance  of a separate me being healed within a world of separate others and a separate world just because of the normal context within which all these healing techniques are traditionally employed.  Any further light you can shed here would be so helpful, Clare.  Thank you so much
