"I looked for Him on the Christian cross, but He was not there.
  I went to Hindu temples and shrines - but nothing.
  I visited the Ka'aba in Mecca, I did not find him.
  I questioned learned scholars, but He outstripped their understanding.
  Finally, when I peered into my own heart - there, and nowhere else, was
His home."

Jaluddin Rumi: Sufi master and poet.
