We all know the self that we see, we know: I am tall or short or of medium height, I am fat or thin. We know the name that has been given to us, whether John or Jacob or Henry. We know also: I have a temper, or: I have my clever ways, I have these merits and these faults, I have this work or this particular way of enjoyment in life, I have responsibilities and cares and sorrows and joys, I have friends and acquaintances and enemies. But all this is not enough. We should consider whether that which we are doing from morning till night, which we are striving after, to which we give a great importance, will remain with us - be it money, fame, name or whatever it may be. Does it make us happy? Does it give us the knowledge of what we were and what we shall be? We should know what we were before, whence we came and whither we shall go, from what all this world has come and into what it will turn.
