It's thus not so much a choice on whether the body chooses to live on or not because the existence of the body is itself largely irrelevant compared to the existence of the mind. Mind matters. What else is there in life if not the mind? How can we live without a mind? You could sever my head, put my brain in a vat, I'd keep on living and if done correctly, you would keep making me believe that this sensory world is real. But is it? And why would this sensory world matter at all? It seems pointless to engage in sensory stimulation if not to ensure that the mind keeps on living. I am stuck in a body and I'm stuck eating every day because my mind depends on a daily intake of nutrients in order to survive. Eating as an activity is itself pointless even though I can derive physical pleasure from it, but physical pleasure is ultimately seen as of lesser worth than mental pleasure. Nothing beats the sensation when you realize you've figured something out. It's a mindgasm, and engaging in mentally interesting activities is akin to mindfuck.
I'm writing this to you solely because it keeps my mind stimulated and entertained, because I derive mind pleasure from it. I am not that unhealthy to say that I wish to discard my body entirely, I can see the point of physical pleasure, but yes, it's an inconvenience I wish I'd rather not have.
I cannot ignore the callings of the mind and I do not have any interest to block out my mind. How would you do this? It suggests that you as an ego is located somewhere else than in the mind, that you are not quite per se, the mind. When you are the mind, you cannot block it out, why would you want to block it out? It would be akin to trying to nullify your own existencem and as much as I find having a body that keeps me here I still desire to exist.
This is why I think 5s and 9s are often mixed up because 9s think that when they block out their mind chatter they are performing 5 meta-analysis or what is usually referred to this mind chatter of talking to yourself kind of deal in some 5 descriptions. Not because I want to point fingers towards any specific people but there are some notorious 9s in the 5 forum on Personality Cafe who keep using this argument to justify why they are 5s, fully ignoring that the 5 mind isn't so much thinking of yourself in third person as much as it is an ability to meta-analyze more than one perspective at once. Detachment is in fact rather empty and this makes perfect sense because 5s are a detachment type whereas 9s are an attachment type. Detachment is simply to me a way to remove myself from the environment, you're stuck with cold and callous logic at its most extreme, because you stop caring. I should upload some scenes from Darker Than Black that I think perfectly demonstrate 5 detachment because the entire concept of being a contractor is very 5-8 like.
