A wise old owl lived in an oak,
The more he saw the less he spoke.
The less he spoke the more he heard;
Why can't we all be like that bird?
I found this in Meditations on a Theme, by Metropolitan Anthony.
Metropolitan Anthony Bloom was a quite a character. He was well-educated having graduated in physics, chemistry, biology and eventually gaining a doctorate in medicine at the University of Paris. Not one to sugar-coat or pull punches, Metropolitan Anthony's writings can make you cringe because of their harsh truths. I highly recommend his biography This Holy Man, by SVS Press. The book quoted from above might be out of print, but you may be able to try Amazon or Abe Books.
Metropolitan Anthony reposed 7 years ago this week. May his memory be eternal!
