Getting your mind to rule over your heart is a common theme in Jewish teachings. It's also horribly misunderstood.
Most people, when they hear about the mind ruling over the heart, imagine a cold, calculated and stuck-up neurotic. After all, the mind is all those things. Wouldn't we much rather live with the vivacious, freedom-loving heart?
So we have to explain that when the mind is ruling the heart, it does not mean that the mind is at the top of the chain of command. Nobody wants the mind in charge—you'd never get anything done. The mind may be great at solving puzzles, but it's an incompetent idiot when it comes to real life. Rather, the mind is meant to be but a conduit for the soul.
You see, the soul, being beyond the body, has a higher vision. It also has some great ideas to express. But the soul needs to get the body involved in that vision and those ideas. And it knows the only way that can happen is by inspiring the heart.
