The mantra om mani padme hum is composed of six syllables, each of which has a projection in light and in darkness. The invocation of these energies of transmutation allows one to purify the other and the practitioner can achieve fairness and access the wisdom of the vacuum, in the path to enlightenment.
For Buddhism the number 108 is a special issue. Many of the bracelets used by the monks 108 accounts to count mantras that sing. It turns our ring to tell all the mantras you carry and thus get closer to enlightenment.
The ring is made of steel and has been the mantra “om mani padme hum” engraved on the outside.
