Google Numerology. I am fascinated by it. The number 9 is the end of a cycle. It is symbolised by higher plains and working for greater causes than your own. Humanitarianism is typified by the number 9. The letters I and R are allocated the number 9. There's so much to say about it... worth buying a good book on Numerology to have on hand.

My 3 children have a 3 in their birthdate: 3rd, 13th and 23rd. Interesting.
