Common man likes to be happy and well. He likes to be able to understand things, and he knows his route to freedom lies through knowledge.

Therefore, since 1950 I have had mankind knocking on my door. It has not mattered where I have lived or how remote, since I first published a book on the subject my life has no longer been my own.

I like to help others and count it as my greatest pleasure in life to see a person free himself of the shadows which darken his days.

These shadows look so thick to him and weigh him down so that when he finds they are shadows and that he can see through them, walk through them and be again in the sun, he is enormously delighted. And I am afraid I am just as delighted as he is.
