What point is there in hating the only thing you owe your existence to? I view it as a kind of ideological laziness, an unwillingness to accept that which come before you and will be after you. An insufferance of compromise with the forces of nature. It stresses you out and you feel like you caj'tcdo anything about it, and that usually turns into extractive, oppressive thought. I think your problems lie elsewhere, and nature is your scapegoat.
You refer to your body as a meat flesh prison but that's an incredibly shallow way of perceiving the greatest vessel for existence that we know of. An incredibile marvel of evolutionary engineering, an organic machine abile to develop memories, happiness, pain, instinct and conscience. It is the way for the Cosmos to know itself. It's typical human hubris to dismiss it as "flesh prison" while actually it's the vehicle of our freedom.
