You remember what the Jedi say:
Don’t think — feel
And we all talk in terms of reason and emotion being different things; of thinking and feeling being semi-independent aspects of our state of being. We talk about the "head" and the "heart" as separate vessels for these aspects. But they’re not.
The heart doesn’t really control emotions, it’s just a muscle that pumps blood around the body. And while emotions do have a bio-chemical nature, and as such, are things we genuinely feel, they’re still controlled by the brain; which itself has an electro-chemical nature, and as such, an equally genuine physical presence.
So what is the difference between thinking and feeling? Isn’t it all just in the mind?
