A human being is a part of the whole called by us universe, a
part limited in time and space. He experiences himself, his
thoughts and feeling as something separated from the rest, a
kind of optical delusion of his 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 its beauty. Albert Einstein
