The body is not a pain-generator, it’s a tool that allows the consciousness to experience an embodied existence. You can obviously misuse tools, for example you can hit yourself on the head with a hammer — that doesn’t mean a hammer’s primary purpose is to produce pain.
If you’re having an unpleasant time with your body, it’s likely that you’re misusing it (i.e. stop hitting yourself). It’s like you’re grabbing the wheel of your avatar and steering it into a wall — don’t do that. The body is fully capable of navigating through the world it was born into — allow this process to unfold.
Because of fear and skepticism, you’re using your influence to interrupt your life’s narrative — stop that. Dismiss fear and rebuke skepticism and just go for it, allow your avatar to freely flow in the direction it needs to go. It WILL fight you when you try to impede its journey and you WILL lose. Skip the stress by becoming a pleasant passenger.
Relatedly: when new circumstances arise, life is NOT trying to torture you or scare you, it’s simply presenting you with invitations to engage. These are opportunities to do something new and interesting. Again, don’t let fear or skepticism prevent you from progressing on this path. You CANNOT protect yourself through inaction — you can’t hide from life.
Life only seems like a harsh taskmaster because you’re distrustful. Life is more like a mamma bird that’s pushing you out of the nest — she wants to see you soar. Yet you, being scared, fight to stay in the nest even though it’s uncomfortable and you’ve outgrown it. As you fall from the nest, you keep your wings tucked and refuse to unfurl them. Boom! Of course the landing hurts!!
Something else to consider: the options you don’t prefer aren’t there to irritate you, they’re simply part of the buffet. If you see something you’re not partial to, don’t select it — but don’t demonize it, just focus on the things you do like. Because something undesirable exists, don’t assume all of life sucks — just pass it by and select something that does interest you.
In essence, an absolute external world does NOT exist, the world you experience depends on your focus and emerges from your thoughts and attitude. Fear and skepticism are your enemies here. If you defeat them, it’ll be smooth sailing on an epic adventure through a grand narrative of human existence.
