“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 feelings as something separated from the rest—a kind of optical delusion of his consciousness.  This delusion is a kind of prison, restricting us to our personal desires and to affection for a few persons nearest to us. Our task must be to free from this prison by widening our circle of compassion to embrace all living creatures and the whole nature in its beauty.”
-  Albert Einstein
