If there was one thing, one huge benefit, that emerges in a moment of realizing the truth of the 3 Principles, in my estimation, it would be this:
Knowing, really knowing, that no matter how real your feeling feels, and no matter how real your circumstances are, these two, your real feelings and your real circumstances, aren't, never were and never will be the cause of each-other.
The former does not create the latter or vice versa.
I don't recommend taking my word for it. That would be a waste of time.
First you have to realize, understand for yourself, this entire universe is,
One Divine Thought.
