I found kefira in ? Mishpat hasukim, which says in the last paragraph that the ikkar is to do mitzvos so you can attach your neshama to the neshama of rav nachman and hhis talmid rav nossan. and after doing mitzvos you are connected with them therefore you are saved from din and mishpat, because rav naachman saw how bad the dor was so he promised hashem he will take care of all the neshamos……
sounds christian to me.
