You don't have a brain, you are a brain. You're cognitive consciousness, that which we attribute to being human is localized entirely within your nervous system. Now, there's also consciousness in what you can reveal deep in meditation when you quiet the circuitry of the mind, that which is a reflection of being a unified field of consciousness colloquially called God, Source, or the universe. Let's not worry about that because I'm writing this paragraph last because my schizo brain be schizo-ing. Let's instead discuss what it means to be a nervous system.

Sometimes I really think about the limitations of being what basically amounts to a brain in a vat. What do I mean by this? Well, name something you know that wasn't told to you, or you read, or you were otherwise handed as knowledge. Oh, you've gotten your hands dirty, have you? Got something from some science project you did with your great-aunt Miranda when you were nine? Well, I got news for you, sistah, your eyes, ears, nose, and whatever else you got for sensory organs told you that information, too!

Sad fact time: you never have or will have contact with the outside of the mind. Fun fact time: you don't fukkin' need knowledge of that ish cuz you can learn about something just as detailed as the outside world tends to appear. That thing is yourself. Truly the brain is a mansion with many rooms, each with a purpose. I could spend the entirety of your dismal lunch break regaling you about the imagination hyperzone that I've discovered exists behind your plain old imagination, or the categorical matrix of the hippocampus which stores complex information in knots or otherwise topological strings, but instead I want to briefly touch on something I feel is important in today's reality.

In one of the rooms in your head, you have a framework, or your paradigm, which boils down to being a heuristically processed axiomatic system. Simply put, imagine a pile of sand. Each grain of sand is an experience, and you have a steady trickle of new experiences every moment. Likewise, each grain is weighted differently based on how much faith you have in that experience. You can probably tell that you have a core to your pile filled with dense grains of sand. These are the most cemented parts of you; the things you learned growing up, the most powerful of your traumas, and the most successful strategies you've experimented with. They're hard to move, and so it's hard to change your mind. But, it's not impossible. 

To transmute your soul, you need to feed yourself powerful, novel experiences by stepping far outside your comfort zone. You used to be able to accomplish this by going on a pilgrimage. With no Discover Card in tow, you'd have to go on an arduous journey, reintegrating with communities as you went, making a living however you could. That sort of contrasting lifestyle to what you're used to shows you the relativity of your own operating system. If you eat many profound experiences like they're your grandma's cookies, you're going to wake up one day and realize that you've got a whole new head.

But, it's a shame that the lifestyle obsession of the modern world canceled the plausibility of doing what I just described. You can still travel, but it's different, unless you radically trek to life off grid or be homeless like I did. Definitely would be my recommendation if my FBI agent wouldn't get mad at me for giving unsound advice. But, rambling aside, I'm just going to say that learning new languages and skills, creating and consuming art, and expanding your mind with psychedelics or magick (or both) are some of the most ideal ways to make an impact on your framework.

And we can agree that's an important thing to do in the modern day. People who get stuck, unable to adapt to our exponentially changing world, are going to suffer immensely as the human hivemind evolves out from us being symbiotes with screens to actually manifesting additional forms of cognition. Some people literally won't be able to comprehend this strange new world because they will lack the faith necessary to restructure their perspective. But, you sure the fuck can! 

See, once you move the densest clumps of sand holding you back from your full potential, you won't let the sand in your pile stick to any particular form. Thus, your pile of sand becomes fluid; ever adaptable. By extension, by achieving this form, you will lessen your suffering to the point you can let solid objects pass right through you. Yes, the Buddhists like to say you must perceive and undo the karmic fetters that bind you to the existence-illusion complex, but you can just say unlearn what has been learned. And now you've learned this. Let it be the key to liberating your mind from one of its restraints that are holding you back from your full potential.
