A human being is part of a whole, called by us 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 his consciousness. This delusion is a kind of prison for us, restricting us to our personal desires and to affection for a few people near 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
