I noticed you didn't say Right Side action or right side thought but said Good Side action or good side thought.Proving something using the Theory of Body Signals:
1. Proving a thought is evil: Submit a thought to God that is obviously evil: "God, is it good to murder people in cold blood, even if they've done nothing against you?"
The answer should come as "Evil (Left Side action or left side thought)."
2. Proving a thought is good: Submit a thought to God that is obviously good: "God, should I love and help my fellow man when he needs help?"
The answer should come as "Good (Good Side action or good side thought).
Using the results of these control questions, you should be able to discern, with effort, whatever thought is evil versus whatever thought is good.
WARNING: This theory is not perfect.
Whereas with the evil thought you said "Evil (Left Side action or left side thought)."
Are these "sides" the left and right sides of our brain. Are we conscious of which side of our brain is being used in thought processes?
Maybe I've missed that bit.
But you say we should be able to discern this left and right character.
