My thoughts exactly! If Jurgen Ziewe is right, then there are vast variabilities up there. Mediums never seem to concentrate on what the people they contact are actually doing now. I wonder if this is an inherent limitation, or if @Alex could organise a little experiment using one of the mediums that Julie Beischel validated?
And this is a more comprehensive assessment, though not complete, from the same source - http://adcguides.com/theafterlife.htm
What other mediums do people rely upon? I know of Edgar Cayce, and Leslie Flint are commonly spoken of.
