In studying three dozen peacemakers, I was particularly interested in exploring common themes in their biographies or philosophies. I discovered five such common themes or principles.

The fifth, and most important principle, is the concept of "henosis," or oneness. The video below presents my own spine-tingling experience with henosis.
