Another who approaches this is Walter T Stace in his discussion
  on mysticism.

  In short, a category error. When you're a part of a one-ness
  experience, there's no self or other. You're a "part of" and it
  a "part of"you.

  When coming out of mystical experience, we sound like babbling
  idiots because there's no words in the language to properly
  describe it. As soon as you're not in it, you have a "before"
  and "after" and "during".

  You have a time when you weren't part of - it a "part of you" -
  then there is a time that it's no longer true.

  So people who TRY to describe it always sound odd.
