Is reality a projection from within the mind, or is it an "altered lens" into the outside world? Let's look at the altered lens theory first. Obviously, we are not all looking at the world with the same lens or viewpoint. If that were possible, and we had a consistent moral code of ethics, we would have world peace.

Imagine no wars, conflict, divorce, or crime. It does make you think that John Lennon might have been thousands of years ahead of his time, when he wrote the lyrics for his song, "Imagine." Although, we may not agree with every word, the thought of global harmony captivates the mind.

Is this a reality? At this moment in time, it doesn't look possible. Peace agreements seem so close, and then, an assassination, or a suicide bomb, changes everything. Why is this world not ready for a Mahatma Gandhi, Anwar Sadat, or Martin Luther King, Jr.?

Do we, as a species, need to grow, and mature a little more, or can we make small changes in this world now? You can make small changes by bringing out the inner calm you have developed through meditation practice. If you are still not sure how to proceed, demonstrating acts of kindness to everyone you meet, will do.

At the very least, following the Golden Rule is good for you, and everyone you come into contact with. Remember, "Do unto others as you would have them do to you". - Luke 6:31.
This action will bring your lens into focus.
On the other hand, a projection is a creation from within the mind's eye. This, in turn, gets impressions by receiving images from outside the body, and judges everything.

This classification, and judgment, creates a biased frame of mind that reacts to a world created by the same mind. The problem is - these judgments solidify into concrete beliefs, resulting in a reality of pre-conceived notions. I refer to this as, The Cycle of Judgment Theory, and hope that you clearly understand the cycle.

The result of the cycle of judgment is dangerous, as there is no room for objective viewpoints. Everything is classified as black or white, and there is no room for a "gray area." This particular viewpoint, with concrete beliefs, has no room for change and will not negotiate.

So both realities exist - creating more realities with potential opposites. This explains why we see people justify atrocities. Whenever you meditate, and are able to find objective viewpoints that are good for your mental health, always beware of judgmental people who have no ability to reason or open their mind.
