This exotic-looking keychain made of sandalwood features a Tibetan Buddhism bell carved with the Om Mani Padme Hum mantra in Sanskrit.
Om Mani Padme Hum is probably the most famous mantra in Buddhism, the six syllabled mantras of the bodhisattva of compassion, Avalokiteshvara (Tibetan Chenrezig, Chinese Guanyin). The Dalai Lama is said to be an incarnation of Chenrezig or Avalokiteshvara, so the mantra is especially revered by his devotees and it is commonly carved onto rocks and written on paper which is then inserted into prayer wheels to increase its effects.
The mantra Om Mani Padme Hum is easy to say yet quite powerful because it contains the essence of the entire teachings of Buddha. When you say the first syllable Om it is blessed to help you achieve perfection in the practice of generosity, Ma helps perfect the practice of pure ethics, and Ni helps achieve perfection in the practice of tolerance and patience. Pä, the fourth syllable, helps to achieve perfection of perseverance, Me helps achieve perfection in the practice of concentration, and the final sixth syllable Hum helps achieve perfection in the practice of wisdom.
