One may ask: What do I mean by heaven? Heaven is that place where all is the choice of man and everything moves at his command. Heaven is the natural condition of life. When, on earth, life becomes so entangled that it loses its original harmony, Heaven ceases to exist. And the motive of the soul is to gain in life the Kingdom of heaven which it has lost. Nothing does one attain in life which will give that satisfaction which can only be attained by bringing heaven on earth.
