We've talked a lot about making preparations for emergency situations. Neither of us have done much about it. The swine flu kicked us into action. Yesterday, I bought 40 pounds of rice and a bunch of bottled water. Today, we hit the grocery store and bought a ton of canned goods and lentils. Is it enough for a disaster? Nope. We'd still need all sorts of things but it is a start. It isn't like we can't afford to store some food and rotate it out to a food bank once in a while.
Magicians should be prepared for magickal needs too. What harm is it in laying in a store of appropriately colored candles and cleansing a few chords, parchment, stones, pieces of metal and having them on hand? I am just learning the thaumaturgical angle of things. If you're going to do things to handle life's emergencies, you may as well have the supplies on hand.
