Hi Jim,
I've never heard this preached in this way, but I believe I struggled for many years with the concept of 'laying down my "soul" life', as if my having a soul was at variance with God's will.
Then the Lord spoke to me from Psalm 23 'He restores my soul' and I remembered that Jesus died to [u]save[/u] our souls; after which I stopped using and thinking in that self-destructive terminology.
Later, I found the concept of healing to the soul, healing to the spirit and healing to the mind (for some, these may be wrapped up in the truth that Jesus heals broken hearts), and began to retrieve some sense of inner being, mostly as the Lord Himself healed me in many tiny ways.
I think (without having heard of such a doctrine as you mention), had I not had a Bible and the Holy Spirit, I may have believed part of it! :-o
