I am part of a whole, called by us the Universe, a part limited in time and space. I experiences myself, my thoughts and feelings, as something separated from the rest a kind of optical delusion of my consciousness. This delusion is a kind of prison for me, restricting me to my personal desires and to affection for a few persons nearest me. My task must be to free myselves from this prison by widening my circles of compassion to embrace all living creatures and the whole of nature in its beauty.
