Quote from : Making the Old New Again and Again: Legitimation and Innovation in the Tibetan Buddhist Chöd Tradition Book

Chöd is conventionally and misleadingly seen as analogous to, if not derived from, shamanic initiatory dismemberment visions, as well as dualistic anti-body ascetic practices. Two of the elements most commonly referenced by authors in their "identification" of Chöd and/as shamanism—the dismemberment/sacrifice of the body and "demonology"—are presented in an oversimplistic fashion. In the first instance, the numerous Buddhist precursors for the offering of the body provide ample testimony to the ethical and meritorious status such acts have in the Buddhist imagination. As for the "demonology" of Chöd, one must keep in mind the psychology and philosophy of mind that explicitly undergirds the discourse of Düd [Skt: mārā] in Chöd.
