Beauty or real beauty, whatever you may call it, is just a concept that can only be defined by you. This isn't only subjective but is also changing over time. We look at things or people and say they're beautiful, but time will come when we will no longer see it that way. And since we look at things differently through our personal filters such as culture, experience, education, and religion, then we create different images of beauty in our mind. Some may associate it with physical appearance, while some people look beyond that aspect. But that doesn't mean one is right and the other is wrong because then again beauty takes varying definition.
As Confucius said it, "Everyone has beauty, but not everyone sees it." Hence, we should not seek to find beauty in the eyes of another because we are all unique creations, and we are all beautiful in our own way.
