Peace that is based upon a circumstance is not spiritual peace. For me, spiritual peace is both the experience of one’s True Nature (which is peace itself), and a general perspective on life. To perceive through meditation and the grace of God that your True Self is eternal and indestructible is the source of a peace that cannot be shaken, and does not oscillate as circumstances inevitably change. It is as if one is watching a movie that has all sorts of ups and downs, thinking that they are an actor in the movie. Then they realize that the Watcher of the movie cannot be affected by the images that are, in reality, merely entertaining illusions.
Meditation does not solve all of one’s problems, for we must still do our duty, serve others, and remain subject to the law of karma as long as we are on Earth. But spiritual realization catalyzed by deep meditation can give us access to a Peace that is beyond the constant ups and downs of life, and the gains and losses of karmic fortune. People may pass out of our lives; we may lose all our wealth and talents; everything we love, and even our body, will someday be taken from us. The wise, however, never grieve about this natural schema. For the peace of God, which comes from understanding that you and God are eternally One, can never be taken from you. To realize this for yourself is truly a priceless gift beyond any means of comparison!
