A human being is a part of the whole, called by us "universe," a part limited in time and space. We experience ourselves, our thoughts and feelings as something separate from the rest, a kind of optical delusion of our consciousness. This delusion is really a 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 understanding and compassion, to embrace all living creatures in the whole of nature and its beauty.
