We've all heard some songs about some lonely heart, but if we look more deeply into this idea we may be able to glean something of personal and spiritual significance. Something that points us to an existential experience of division, and a longing for union.
What is a lonely heart? Can you imagine it? How it might feel, to have a sensation inside of you that makes you aware distinctly of your ultimate aloneness? This is experience is not one you can control, whether you are surrounded by a hundred loved ones, or no one.
Deep down you may sense that the stories you have been telling yourself for what seems like forever, are ultimately vacuous. Whatever it is you have been working towards is rendered transparent, a proverbial carrot inside of your hamster wheel.
You can try to change it, start a new hobby, meet new people, deepen your spiritual practice but nothing you seem to do helps; you feel just as alone after as when you started. I would surmise you have a couple of options, and for simplicity I will keep it at that. You can continue to try to find ways to ameliorate or numb the feeling in your chest. That is a good option- it seems to work for most people. You can create new projects which may bring relative fulfillment to you... also a good option. You could turn towards that lonely heart, allowing yourself to feel its contours, colors, textures and shapes.
What would happen if I were to allow myself to feel my lonely heart? Who would I be if I were nobody, if whatever ultimate significance I attributed to my own projects was seen through to the utter simple chaos that is behind every waking moment, the unimaginable indefinable openness from which time itself arises and departs. What would be left if I could no longer maintain the sense of my distinctness in the face of all of existence?
Our hearts can be broken when we discover that who we thought we were was just that; a thought. An ongoing story with a predictable rhythmic chatter. My lonely heart leads me through this recognition, that I have never truly known anybody, because no one has ever truly known themselves. Thus I am caught between the desire for permanence and the continual destruction and recreation of every thought I have ever had. Such a heart oozes with a desire for the spacious abundant abode where nothing can be lost or gained. And that in that realization itself is freedom.
No one can hold onto anything, ever... and our whole society is built on the delusion that there is someone who can hold onto something. Your experience isn't yours, your possessions aren't yours, your family isn't yours. We are always looking for something to hold onto, it is only human.
What would happen if you let your lonely heart break itself open? You can follow the hurt so deep that it turns into the creation of the universe, only if you stop running. When we listen to our lonely hearts we can break ourselves open, to find that pain and pleasure aren't as separate as we have made them out to be. Both exist in a free-flow, changing constantly. When we know this, we don't need to identify so strongly with our pain, or with our pleasure. We can cultivate true equanimity, peace, and freedom.
