This is such a common metaphor but it really doesn’t hold up to scrutiny. What we really mean is that we make one argument to represent our desires and another argument to represent our fears and we bounce them back and forth inside our own heads in the hopes that we can stay balanced and on some fictitious tightrope of life. But of course there is no tightrope. That would imply there is some correct way to live and there isn’t. There is no right step for you to take. It’s not a battle between your mind and your heart for the right thing. You’re just going to pick a thing, not the right thing. So the battle in your head is over an answer to a question that doesn’t exist, meaning the entire mental exercise is a waste of time. So since both the heart-voice and head-voice are both just your hopes and your fears being relayed back to yourself, that’s all pretty meaningless. You might as well just save yourself the drama and be quiet-minded instead. Because without constructing the notion of a rope that you then need to balance on, the possibility of making a mistake disappears. And that’s what real freedom is. The freedom to get off the narrow confines of the rope, where any wrong move is sure to tumble you out of existence. Instead you can be firmly on flat ground, free to move in any direction you choose. Stop your mental arguments with yourself. Get off the rope. Go peaceful instead. Live with a quiet mind. The rest is all theatre.
