Ecclesiastes said that "all is vanity," Most modern preachers say the same, or show it By their examples of true Christianity: In short, all know, or very short may know it.
The alchemists spent years in their laboratories, observing the fire that purified the metals. They spent so much time close to the fire that gradually they gave up the vanities of the world. They discovered that the purification of the metals had led to a purification of themselves.
Whether a man hides his bad qualities and vices or confesses them openly, his vanity wants to gain an advantage by it in both cases: just note how subtly he distinguishes between those he will hide his bad qualities from and those he will face honestly and candidly.
Things said or done long years ago Or things I did not do or say But thought that I might say or do, Weigh me down, and not a day But something is recalled, My conscience or my vanity appalled.
