Ting Shas are traditionally used in Tibetan Buddhist culture for the end or start of meditation or used by yoga practioners signaling the end of session. Many school teachers these days use these cymbals to get the students attention naturally. These are ting shas hand crafted in Nepal, made from 5 metals, the cymbals are tuned to different keys to make the sound waves reverberate off each other and ring out for quite some time. The mantra cymbols have the compassion mantra, the 8 auspicious symbols have the eight lucky symbols of Tibetan Buddhism, the dragon symbolizes longevity and prosperity. Your choice.
