Colleen, are you saying that when I get sick it's because of germs and not because I washed my obi, which resulted in loss of Ki and subsequent weakening on my body's life force? And after washing the obi, I don't have to harmonize with a tree to replenish my Ki in an effort to prevent illness?
Hey, I just covered three different threads with that.
On a more serious note, I'm pretty certain that I've never washed an obi. The middle section of my body doesn't seem to sweat much and for whatever reason, my obi has never appeared to need a good washing. But, Colleen makes a good point and so I'm going to start hand washing my obi whenever I wash my hakama.
