 Defenders of PCEs depend on alleged references to pure consciousness in the mystical literature. One example is the Buddhist philosopher Paramaartha (499–569) who stated explicitly that all of our cognitions were “conditioned” by our concepts save for the “unconditioned” experience of the emptiness of phenomena (Forman 1989). Another example is Meister Eckhart who described a “forgetting” that abandons concepts and sense-experience to sink into a mystical “oblivion” (Forman 1990, 121–159). In addition, Robert Forman has testified to a PCE he himself underwent (Forman 1990, Introduction).
