The Power of Positive Confession is steeped in Eastern mysticism.
Buyer Beware that you can be led down a dangerous path.
It is wise to investigate it for yourself. One incident does not build an iron clad case for it as I recognize that hypochondria can be a real thing.
But simply declaring something to be so does not always change it. It will if you convinced yourself something is wrong in the first place, but if not, no amount of declaring anything will change it. It’s God’s sovereign hand that changes things.

confessing the Word of God as truth is definitely NOT eastern mysticism. It is Biblical.
