There exists 1 million and 1 ways to prove that circumstances or the past do not hold the power to dictate how you feel. There are an endless array of examples where identical scenarios seem to elicit a wide range of emotions even within one person. It's quite easy to see, there exists a deeper order at work - a higher organization, behind the human experience. Frequent as it is, change is clearly possible despite the particulars of our lives. We are not locked in by the outside.
There have been many attempts to create a comprehension that can be taught such as the metaphor of Mind, Consciousness and Thought. It has been described as Truth, Light, Energy, G-d, Wisdom, Oneness, Is-ness and the list goes on. There have been endless metaphors and stories, books, charts and graphs, conversations and speeches, seminars and workshops (and these emails of course!)
Each expression is helpful. Every time you engage in any form of learning you have opened the door even wider for something fresh to enter your life.
Our intellect, consciousness, awareness or evolution is never limited by circumstances or the past, because we are only limited by the Will of G-d. The Will of G-d runs on a very precise schedule of perfection. As we get aligned with this truth the process becomes so much lighter as more and more illogical rumination naturally falls away simply due to insightfully understanding the unifying source of life.
