Om Mani Padme Hum- (Sanskrit) Om Mani Peme Hung (Tibetan) is the oldest and most well known mantra of Tibetan Buddhism. "Om, jewel in the lotus, hum." The first syllable, OM, is not a word but an evocation of spiritual power and the presence of the absolute. It is known throughout Asia in several religions, especially Hinduism. For Tibetan Buddhists, "jewel in the lotus" represents bodhichitta and the wish for liberation from the Six Realms.
