Btw, never take compliments like "brilliant" and "ingenious" too seriously. These words get bandied about much too often, and it's hardly ever appropriate.
Sometimes when I read or write, it's with a voice I haven't heard before. It doesn't sound authentic to me. That's my mind being loud, and it acts as a dirty filter that inhibits pure words from flowing freely.
But could you elaborate more on what you mean by a 'filter' as opposed to a 'selfless zen state'?
