Abraham, L. Ron Hubbard, Someone Else?
Abraham Hicks call this the Emotional Guidance Scale. Hubbard called his The Tone Scale. Notice the similarities--the movement from fear to anger to boredom to contentment to enthusiasm.
Perhaps they didn't even bother going back that far and just ripped it out of Dr. David R. Hawkins' 1995 Power vs Force.
It does have more similarities with Dr. Hawkins' scale.
