In my early life I made two very important discoveries. In the first place I discovered that making money was easy. And in the second place I discovered that making money and spending it foolishly was completely meaningless. I knew that this was not what I was here for, but at that time (this was many years ago), I didn't know exactly what I was here for. It was out of a very deep seeking for a meaningful way of life, and after having walked all one night through the woods, that I came to what I now know to be a very important psychological hump. I felt a complete willingness, without any reservations, to give my life, to dedicate my life to service. I tell you, it's a point of no return. After that, you can never go back to completely self-centered living.

And so I went into the second phase of my life. I began to live to give what I could, instead of to get what I could, and I entered a new and wonderful world. My life began to become meaningful. I attained the great blessing of good health; I haven't had a cold or headache since. (Most illness is psychologically induced.) From that time on, I have known that my life-work would be work for peace; that it would cover the whole peace picture - peace among nations, peace among groups, peace among individuals, and the very, very important inner peace. However, there's a great deal of difference between being willing to give your life, and actually giving your life, and for me, 15 years of preparation and of inner seeking lay between.
