It is made by hand with an alloy of 7 metals, symbolizing each one a planet: gold (Sun), silver (Moon), mercury (Mercury), iron (Mars), lead (Saturn), tin (Jupiter) and copper (Venus) . Its thick walls produce sounds of extraordinary duration. It also vibrates when the mallet slides around the outer top edge by varying the pressure or speed.

Tibetan bowls were used 4000 years ago and had astrological, therapeutic and secret ritual uses. It is said that tolling them eliminates tensions in the body, cleanses the environment of negative energies and creates an instant of peace. Each bowl has a unique sound and each person a peculiar way of playing according to their character or their mood. If several are played at the same time, the resulting vibration multiplies the effect of the sounds.

"Listening to the bell, I feel my afflictions begin to dissolve, my mind calms down, my body relaxes. A smile is born on my lips. Following the sound of the bell, my breathing brings me back to the safe island of full consciousness. "
