My incite on a quote about art.

I came across this quote which I found to be really interesting. Ralph Waldo Emerson once said, "In art the hand can never execute anything higher than the heart can inspire." I believe this is true. I believe this because when it comes to art, it comes not from the outside world, nor from the mind, but it comes from the emotions, the heart. Yea! Sure art is inspired from what we see from the outside world and it does consist of processing on the cognitive level, but unless your emotions are truly in tune with what you are creating then what is the sense of creating? If the enjoyment isn't in what you are creating and you are just doing because you have to or you feel like you have to, then I feel like even though that still may be art, that is cheating. Think about it like this, if you have a rock and you love the rock with all that you have, wouldn't you care for it, tend to it never leave it? This is because you love and care about it with your all and you invest time in it because you want to. No lets think about it in this perspective, you are given a rock and are told to care for it, even though you don't want to you do it anyway, however you do it with little effort, with little enthusiasm and without devoting as much time and care into it as you would if you truly wanted to. The rock is art and you the caregiver are the artist and unless you care about the thing you are doing and truly do it from the heart it won't mean much. In art your hands, your feet, your body, what ever medium you use to create your work of art it can never be higher than what your heart wants it to be , because art is where the heart is. So with that said, what does the quote above by Emerson mean to you?
