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 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
