Imagine that this world was actually designed entirely by a highly specialised diagnostic machinery that was able to read into your brain, into your thoughts, who had access to the information about your every past experience, and designed every tiniest detail of this world to fit into your personal mind structure. Imagine everything is custom-made to fit your personal taste, experiences, fears, every little detail in the room you sit is somehow connected to something you have experienced in the past. Every thing in your surroundings was put there so that it implicitly brings up some certain memory. Every sound you hear was especially engineered to resonate with you in some very specific way. It's a hi-tech system personalised only for you.
And now the best part: in fact this is how it really is. The world you see exists only in your head and was indeed custom made to fit you. This highly specialised machinery is evolution.
What I want to say is that absolutely nothing in our heads that happens for no reason. I just saw one person who creates really uncomfortable feelings inside me that are connected to feeling unworthy. And a second later I had a song in my head that I could not get rid of. I just now asked myself "what is that song about" and it is about being a vulnerable human being and not letting anyone tell you who to be. If only we learned to be more mindful about ourselves, would we learn so much..
