The intuitive mind is a sacred gift.

A theory is something nobody believes, except the person who made it. An experiment is something everybody believes, except the person who made it.

Only a life lived for others is a life worth while . I have no special gift. I am only passionately curious . I want to know God's thoughts... all the rest are details. Joy in looking and comprehending is nature's most beautiful gift. It's not that I'm so smart , it's just that I stay with problems longer.

The most incomprehensible thing about the world is that it is comprehensible.

That which is impenetrable to us really exists. Behind the secrets of nature remains something subtle, intangible, and inexplicable. Veneration for this force beyond anything that we can comprehend is my religion.

Our situation on this earth seems strange. Every one of us appears here involuntarily and uninvited for a short stay, without knowing the whys and the wherefore. In our daily lives we only feel that man is here for the sake of others, for those whom we love and for many other beings whose fate is connected with our own. I am often worried at the thought that my life is based to such a large extent on the work of my fellow human beings and I am aware of my great indebtedness to them.

I have remained a simple fellow who asks nothing of the world; only my youth is gone - the enchanting youth that forever walks on air.
