My idea of heaven is not unearthly. Heaven is here -- you just have to know how to live it. And hell too is here, and you know perfectly well how to live it. It is only a question of changing your perspective, your approach towards life.
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, if you become a condemner, a poisoner, then the same earth turns into a hell -- but only for you. It depends on you where you live, 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.
