"The mantra Om Mani Pädme Hum is easy to say yet quite powerful,

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. Päd, 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.

"om mani padme hūṃ", written in Tibetan script on a rock outside the Potala Palace inTibet

"It is very good to recite the mantra Om mani padme hum, but while you are doing it, you should be thinking on its meaning, for the meaning of the six syllables is great and vast... The first, Om [...] symbolizes the practitioner's impure body, speech, and mind; it also symbolizes the pure exalted body, speech, and mind of a Buddha[...]"

"The path is indicated by the next four syllables. Mani, meaning jewel, symbolizes the factors of method: (the) altruistic intention to become enlightened, compassion, and love.[...]"

"The two syllables, padme, meaning lotus, symbolize wisdom[...]"

"Purity must be achieved by an indivisible unity of method and wisdom, symbolized by the final syllable hum, which indicates indivisibility[...]"

"Thus the six syllables, om mani padme hum, mean that in dependence on the practice of a path which is an indivisible union of method and wisdom, you can transform your impure body, speech, and mind into the pure exalted body, speech, and mind of a Buddha[...]"

-- H.H. Tenzin Gyatso, 14th Dalai Lama, "Om Mani Padme Hum"^[7]
