This sentence implies a life attitude, a simple philosophy in daily life. However, as we often compare beauty to an art work, beauty is, in the first place, supposed to create aesthetic sense. Can we call a pile of garbage "natural beauty", even which contains much nutrients? So, in my opinion, beauty should be a good (if we cannot reach 'perfection') match of the elegance outside and the richness inside. Actually, this can be attributed to the question "how men appreciate women"! Someone argue that it is a lie when a man tells his lover "I do not care how pretty you are..." What do you think?
