      Thanks, Bob. Pardon the top post,
      but the article is long. It is interesting
      that the term "zombie" (walking
      dead) was chosen.

      In spiritual or theistic terms, this
      "inner knowing" would be regarded
      as holy - as in Holy Spirit or
      Paraclete (one who walks beside).

      In the most religious sense, a
      passage of scripture from the
      Book of Proverbs in the OT
      comes to mind:

      "Lean not upon your own
      understanding. Acknowledge
      me in all your ways and I will
      direct your path."

      In the Mystic Heart Meditation
      this "inner knowing" is referred
      to as a "wisdom whisper from
      the heart" or an experience of
      pure intuitive consciousness.

      The premise is that we have
      been so socialized to consider
      our conscious, rational, linear
      process as THE way to know
      that we have forgotten or lost
      touch with our intuitive capacity -
      and meditation (silencing the
      inner chatter) is a means to
      tapping into this inner knowing -
      or what I interpret Ramana Maharshi
      to have meant when he referred
      to the I-I.

      Just some early coffee-induced thought
      bubbles from the waking zombie.
