You must imbue your life essence into the jade. It is not mere rock - it has its own energy, and this transfer of energy between the wearer and the jade is what gives it life.
1986, 1998, 2010 - all Years of the Tiger. My year. What significance does this have? We're warned as children that you should be extra cautious during your own year. Last time around, at 12, I cracked my glasses, resulting in 7 stitches over my left eye. I was about 1/4 inch away from blinding myself, so this time around, I'm heeding that advice.
That's why we have these. Jade pendants, on red string, are said to bring good luck. The jade is carved with your animal sign - can you see the crouching tiger? Just ferocious, all tension and lethal power, waiting to pounce. I actually wore this pendant, dutifully, when I was 12. I have no idea where it's been for the last 12 years, but here it is again.
The more you handle jade, the more you transfer your energy to it, the shinier, and glossier, and smoother it becomes. A jade tiger.
