robert sharf points out that "experience" is a typical western term, which has found its way into asian religiosity via western influences. the notion of "experience" introduces a false idea of duality between "experiencer" and "experienced". in kensho there is no duality of observer and observed. "pure experience" does not exist; all experience is mediated by intellectual and cognitive activity. the specific teachings and practices of a given tradition may even determine what "experience" someone has; this means that this "experience" is not the "proof" of the teaching, but a "result" of the teaching. a pure consciousness without concepts, reached by "cleansing the doors of perception", would be an overwhelming chaos of sensory input without coherence.
