Every passion has it’s language; every language is itself an art. Whether an individual is crafting a simple letter or writing a thousand pages for a novel; whether she is singing a song straight from the heart; whether he is sculpting the muse from his dreams; or whether they are doing something entirely new and unique. There is a language that is held within every art, and everything is an art. Everything has a story to tell, and sometimes only the creator will know or understand that story, in whole or in part.
You can stare at a piece hanging before you, and even though you try, never understand. It is not your fault, nor the creators, nor even the piece itself; there is simply no way for you to understand it. Accept the beauty as it is, whether that comes from a true feeling of beauty in the piece or respect for the crafting of it. All things are beautiful, both the simplistic and the very intricately detailed.
Every individual will use them in his, or her, own ways. Some things may not be appealing to others, and that is okay; I know with certainty there are things that I cannot stand, but that does not make them wrong. The best way to learn the stories is to observe and ask, which is even more actionable.
Ask for the story; seek it out; it will likely be worth your time.
