"A human being is part of the whole called by us universe, a part limited in time and space. He experiences himself, his thoughts and feelings as something separated from the rest, a kind of optical delusion of his consciousness. This delusion is a prison for us, restricting us to our personal desires and to affection for a few persons. 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."--Einstein
