According to Osho, you create misery by choosing—taking sides fragments you, sets you against parts of life and yourself. Choice breeds inner conflict and the illusion you must fight existence. Bliss arises from choiceless awareness: relax, trust the whole, and respond totally to what the moment brings—love when love flowers, meditate when silence calls—without preference or suppression. Then wholeness replaces misery.
You feel miserable because you keep picking sides and fighting life; stop choosing and just flow with what comes, and peace appears.
