You are absolutely right. To tell them alters do not exist discounts their experience. There is healing that comes from acknowledging alters and by casting them aside one only halts the healing process. I find far too many disregard alters by thinking the problem lies with the host so they should only deal with the host.

You have to go forward to go back...

If you want to get back to a healed host you have to go forward through alters to get back to a state of wellness.

I wish you peace.
