I was thumbing through Living the Qabalistic Tarot ~ Applying an Ancient Oracle to the Challenges of Modern Life this morning, and saw a quote something like:
Basic physics tells us that anything hung in the manner of the Hanged Man will swing back and forth like a pendulum until it is perfectly centered.
I have to paraphrase because I don’t have the book with me. But I thought that was a neat thing to say about the hanged man.

Another idea from the same book: Last night a group of us got together and did a numerological mapping from important dates down to major arcana cards, and then we meditated on the card to see what might pop out at us. Most of us picked a deck that we haven’t used much, so that we wouldn’t get bogged down with meanings we’ve learned to spit out as a reflex. The results were interesting, I think.
I go back and forth about how much faith I put in numerology, but I have to admit that the patterns you can uncover are interesting. Like, if you take the day I started dating my ex-wife, and the day we split up, they both reduce to Card 8: Strength (or, alternately, Card 8: Justice, depending on the deck you use). It can be interesting to meditate on how the card relates to both events.
Another interesting pair we found last night: July 4, 1776 (US Independence Day) and September 11, 2001 (World Trade Center Attacks) both reduce to Card 5, the Hierophant.
You get the idea!
If you want to do the reduction for a date of your own, you just add up the numbers in the date, then add up the digits. If you get a number higher than 22, just add up the digits again to further reduce it. For instance, today is 8/14/2008. 8 + 14 + 2008 = 2030. Add up the digits 2 + 0 + 3 + 0 to get 5: the Hierophant.
