It can only be achieved by understanding. And so for centuries, mankind has turned to religion for the understanding that brings peace. War is the reflection of man's own inner turmoil magnified, the result of the failures in the common consciousness. Peace is more than the absence of war. It involves collaboration and binding agreements.
Peaceful coexistence is the reflection of man's inner tranquility, magnified.
Because of its bloody past, organized religion around the globe has earned a questionable reputation. As a result, many turn away from the religious instruction of their youth or refuse to even consider any line of thinking that is metaphysical. They believe freedom from religion is the same as freedom of religion. Nothing is farther from the truth. Until we are willing to consider ideas that are new to us, ideas that stretch the way we think, we will continue to set our destiny of repeating the mistakes of our ancestors.
