"Across the Universe" and Other Cravings

I've been in the mood again for one of my favourite movies, Across the Universe, lately. I wrote about it before. The video below is a scene from the movie in which Evan Rachel Wood covers the beautiful Beatles' song "Blackbird".



Whenever I crave for something, be it food, or music, or visual stimuli, I always wonder what is the cause for the craving. You see, our cravings are signs that our being has a lack of something. As you probably know, I'm mostly a flexible vegetarian so I almost never eat meat, and don't enjoy red meat and if I were to eat it, it has to be cooked very well done. However, on occasion, once a year maybe, I may suddenly crave medium done red meat. What this tells me is that my body is lacking iron. Usually when I take an iron supplement or just eat some spinach the craving disappears. The same principle applies to other cravings in our life. What I'm wondering is, what is it in or about Across the Universe, that my soul has a need for?
