A person who has good thoughts cannot ever be ugly. You can have a wonky nose and a crooked mouth and a double chin and stick-out teeth, but if you have good thoughts they will shine out of your face like sunbeams and you will always look lovely.
It can be hidden only in complete silence and perfect passivity, but its disclosure can almost never be achieved as a willful purpose, as though one possessed and could dispose of this "who" in the same manner he has and can dispose of his qualities. On the contrary, it is more than likely that the "who," which appears so clearly and unmistakably to others, remains hidden from the person himself, like the daimon in Greek religion which accompanies each man throughout his life, always looking over his shoulder from behind and thus visible only to those he encounters. This revelatory quality of speech and action comes to the fore where people are with others and neither for (the doer of good works) nor against them (the criminal) that is, in sheer human togetherness. Although nobody knows whom he reveals when he discloses himself in deed or word, he must be willing to risk the disclosure.
