You know... I'm not sure that this is actually all that fundy but rather a horribly garbled retelling of the religious traditions of another culture.
Specifically the tribal traditions in parts of Mongolia and Northern China where the local shaman is voluntarily possessed by/channels the spirits to convey messages etc and so one. While India is the culture that gave us the word 'avatar', in the original sense of a person being a mortal vessel for a god.
Of course neither is all that different from 'being touched by the Holy Spirit' especially in the charismatic traditions or the idea of Saint performing miracles in the Catholic and Orthodox traditions respectively. So yeah, some minor fundy points for the enthocentrism, but not as off the wall as it first appears.
