A human being is a part of the whole called the "universe," a part limited in time and space. He experiences himself, his thoughts and feelings, as something separate from the rest, a kind of optical delusion of...consciousness. This delusion is a kind of prison for us, restricting us to our personal desires and to affection for a few persons nearest to us. Our task must be to free ourselves from this prison by widening our circle of compassion to embrace all living creatures and the whole of nature in all its beauty. Nobody is able to achieve this completely, but the striving for such achievement is in itself part of the liberation and a foundation for inner security.
