We will be able to depart this life with the quiet peace-giving notion, that we were permitted to contribute to the happiness of many who will live after us. In our long lives we endeavored to unfold the collective consciousness. In our lives we have known hell and heaven; the final balance, however, is that we helped pave the way to dynamic harmony in this earthly house. That, I believe, is the meaning of this live.
