"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."

The popular and scientific views of "race" no longer coincide. The word "race," as applied scientifically to human groupings, has lost any sharpness of meaning. To-day it is hardly definable in scientific terms, except as an abstract concept which may, under certain conditions, very different from those now prevalent, have been realized approximately in the past and might, under certain other but equally different conditions, be realized in the distant future.
