For me, as a physician, there is no surer evidence that something glorious and wonderful lies beyond our mortal existence. Death is not an end. It is a new beginning. It entails a magnificent reunion with God and all the wonderful souls that we've ever loved or will love. This is our destination when we pass over. Dying is not the end but rather a shift to a fresh form of life, a new and glorious manifestation of ourselves. In this regard, death would seem to be just another dramatic transition in a continuing cycle, similar tin quality to birth. We jettison our mortal shell as we pass from one life form and consciousness to another, more wondrous than the latter.
If you give your life as a prayer, you intensify the prayer beyond all measure. To attain inner peace you must actually give your life, not just your possessions. When you at last give your life bringing into alignment your beliefs and the way you live, then, and only then, can you begin to find inner peace.
