 Is the content of mystical experiences “given” to a mystic, or is it constructed by the mystic in accordance with the mystical, religious, and cultural tradition in which he or she is embedded? First consider the possibility of “pure consciousness events” (PCEs) — mental events that allegedly involve an “emptying out” by a subject of all phenomenological qualities and content (including concepts, thoughts, sense-perception, and sensuous images) and yet remaining awake, thereby leaving only unconditioned consciousness. Do such events occur? And if they do, how significant are they in mysticism?
