Beauty is in the eyes of the beholder.
You think somebody is bad-looking? Ask their mother or their grandmother.  They never think their children are bad.
And, what do you mean by good-looking and bad-looking? How long can it stay?  The most good-looking,  after sometime don’t look so nice. It is not in the outer appearance, it is the spirit, the inner soul. Look at the spirit inside, there is inner beauty. That beauty of the spirit is undying. It increases day by day. It increases with age also. Wisdom and maturity bring so much beauty.
Beauty is not just some appearance. Similarly, ugliness is not out of appearance. Somebody may look very good with good makeup,
but if their heart is very ugly and the mind is all twisted and full of negativity,
however nice they may appear, their vibrations will tell you that they are not beautiful.
