Me as I think I am and me as I am in fact - sorrow, in other words, and the ending of sorrow. One third, more or less, of all that sorrow that the person I think I am must endure is unavoidable. It is the sorrow inherent in the human condition, the price we must pay for being sentient and conscious organisms, aspirants to liberation, but subjects to the laws of nature and under orders to keep on marching, through irreversible time, through a world wholly indifferent to our well-being, toward decrepitude and the certainty of death. The remaining two thirds of all sorrow is homemade and, so far as the universe is concerned, unnecessary.
