The heart wants what it wants right?
Well....the heart is an involuntary muscle working non stop without you even thinking about it. So therefore whatever the heart wants is not logically thought out and does not align with with reality. Your desire could be a fabrication and is pushed aside behind everything else that happens in the universe that actually matters and has significance. What the heart wants is not what you need and although it may feel as if you might die without it...you will live. Pain is nothing but the mind sending signals telling you to stop doing what is causing said pain. So stop chasing figments of your imagination.
