Beauty is in the eye of the beholder is a relative maxim but a thorough check into this subject matter really shows so.
If we say beauty is in the eye of the beholder, then the person who is observing gets to decide what is beautiful. This common saying simply means beauty doesn't exist on its own but is created by observers.
It is also mysterious how Even a blind and veiled man can tell when he perceives beauty. So isn't beauty more of a conception than just the facial.
Beauty doesn't just lie on the face but more within the inside. Be beauty inside and out.
