The Earth is beautiful. If you start living its beauty, enjoying its joys with no guilt in your heart, you are in paradise. If you condemn everything, every small joy, then the same Earth turns into a hell. It is a question of your own inner transformation. It is not a change of place, it is a change of inner space. Live joyously, guiltlessly, live totally, live intensely. And then heaven is no more a metaphysical concept, it is your own experience.
