“How does one work with a soul in purgatory?”
Ever since I died and returned I physically sense souls whether in or out of a physical body, can read the stored memories in them and frequently can communicate directly with them.
For many years I would focus on helping spirits cross over or leave people’s bodies where they had attached or were stuck. Now I just let them be unless guided to do something. It’s not my mission to combat them, unless as a servant it is His will.
You’re messing with the demonic.
Dead humans are out of our reach and WE can’t help them.
