Singing Bowls
I’m not a yogi or a Buddhist, but randomly surfing the Internet can get you pretty much anywhere. Including shopping web sites. In my case, the word “singing bowl” got my attention. I mean, how can a bowl sing? A 5-minute research on my favorite search engine gave me the answer. Turns out that the bowls don’t literally sing, but they’re used as a support for meditation, trance induction and prayer.
Anyway, if any of you are interested or are looking for such items,you can find them at Crystal Singing Bowls.

Haha I thought the bowls produce some kind of resonance that’s why it’s called singing bowls. Is it ok for a link exchange?
