Kotzer Rambam's psak eliminated demons #670

Kotzker Rebbe (Emes v’Emuna #670) The Kotzker reconciled the contradiction between the view of the Rambam who wrote that shedim (demons) don’t exist with that of Chazal  who mention the existence of demons in many places in the gemorah - by saying originally demons did in fact exist but that after the Rambam paskened that they don’t exist Heaven agreed and similarly paskened and that is why they no longer exist.
