Om mani padme hum belongs to Avalokiteshvara and is the most-recited sequence of syllables in human history by a wide margin. Its literal reading is contested — "the jewel in the lotus" is the usual gloss, and Tibetan teachers generally decline to make the meaning do any work, since the practice is not about understanding it. The mala has 108 beads and a marker bead you do not cross, so counting reverses at each round. In the Tibetan world the mantra is also inscribed on stones, printed on flags for the wind to say, and rolled into wheels: the practice is designed to be delegated to the environment when the practitioner has to do something else.
