A few months ago I went with Beulah to a concert that was entirely one man playing many Tibetan Singing Bowls. He gets them himself from Tibet, where he stays with the people who make them. He could make water spray out of the bowl just with the vibration of the sound.
I have a Tibetan Singing Bowl that I treasure greatly; it was a gift from gamergrrl when she came back from Mongolia. It sits on my shelf, looking beautiful. Usually.
Tonight I took it down to try to play it. At first, I thought there was no sound at all. But I played with it, slowly and carefully, to get the hang of it. There was a faint bell=like sound. And then I realized suddenly that there was a loud, musical ringing tone that seemed to be all around me - but it could only be coming from my bowl.
Happy with my experience tonight, I'm going to try again tomorrow. It seems a beautiful kind of meditation.
