Rudraksha beads are very rare and precious.  Spiritually they have been worn and used for meditation, japa mantra, and pujas/fire ceremonies for many centuries. Asian Yogis and Monks found that merely wearing the Rudraksha beads gave them astonishingly tremendous amount of tranquility, concentration that helped them meditate for a long period of time with spectacular control over their mind. Buddha wore Rudraksha beads, along with the Dalai Lama, Gandhi, and many enlightened Indian yogis.
