A human being is part of the whole called by us a universe - a part limited in time and space. He experiences himself, his thoughts and his feelings, as something separate from the rest, a kind of optical delusion of his consciousness.

This delusion is a kind of prison for us; it restricts us to our personal decisions and our affections to 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
