Eckhart Tolle is one of my favorite people.  He explains what it means to be in the moment, every moment and just to live moment by moment.  This is the way to have peace in your life.

Additionally, accepting what is stops all internal and external conflict.

This is a great video, although the quality of some of the clips is not the best the message does come through loud and clear and even shows the great sense of humor that he has.
