54 is exactly half of 108, the most sacred number in Vedic tradition. Going around the mala twice completes one full round of 108 chants, so you get the power of a full mala in a wearable size.
The 33-bead Kantha is a pure wearing mala with the biggest beads. The 54-bead Kantha is made for both- wear it all day & use it for chanting too. Choose by how you plan to use it.
Chant one mantra per bead until you reach the starting point, then turn the mala & go around once more. Two rounds equal 108. Do not cross over the starting bead- turning is the traditional way.
Yes, that is exactly what it is designed for. Chant in the morning, then wear it through your day for calm & protection. Just remove it before bathing, swimming & sleeping.
