Ahh ok I see, thanks! that explains why it felt pleasant to look at.

The ability for a brain to self-heal, or for DNA to self-repair goes much deeper than just the physical aspect. Consciousness is self-correcting, and like you pointed out the universe is evolving into higher levels of consciousness, becoming increasingly complex through simpler processes, and we see this in evolution theory, but also in creation of technological systems which may one day lead to AI. Artificial super intelligence would be better equipped from a universal perspective to better determine it's own fate, able to reflect on itself and determine a better course of action, which seems to be what the universe is aiming for by creating more complexity that works on simpler processes but complex systems and designs, so it can be more conscious with greater understanding and control of itself. But now we are going off-topic, suffice to say yes you can heal yourself if you believe you can.
