According to Osho, the body is a natural instrument that will register heat, cold, hunger and pain; awakening doesn’t cancel biology. What changes is identification: the witness knows, 'I am not the body,' so sensations don’t become suffering. When sympathy or resistance drops, even 'cold' can be enjoyed, like his toes enjoying cold. Discomfort persists; bondage to it dissolves.
Your body still feels things, but if you watch without clinging, they don’t hurt you inside.
