A scientific approach to silent consciousness

[摘要] All mammals show the physiological correlates of waking, dreaming and deep sleep. Many contemplative traditions propose a fourth state of consciousness, “silent consciousness,” defined as consciousness without reportable contents. For example, the Mandukya Upanishad, one of the root texts of Vedanta philosophy, explicitly claims a fourth state of “consciousness without content.” (Sharma, 1997) The classical summary of yogic thought, Patanjali's Yoga Sutras, recommends “Let there be soundless repetition of (the inner mantra) OM and meditation thereon.” (Feuerstein, 1989). The classical texts of Zen Buddhism also cite consciousness without reportable contents many times (Reps and Senzaki, 1998; Hori, 2000). About a fifth of the world population is Hindu or Buddhist.
