The degenerative character of Bardo life is corroborated by the spiritualistic literature of the West, which again and again gives one a sickening impression of the utter inanity and banality of communications from the ‘spirit world’.
Evans-Wentz directly names and critically evaluates the ‘spirit world’ concept, contrasting Western spiritualist communications unfavorably with Tibetan eschatology while acknowledging the scientific hypothesis that such reports are unconscious projections.
