Om Mani Padme Hum
OM Mani Padme Hum
This is a very short 6 syllable mantra that is repeated in verses of 4 lines. It has been translated as "jewel in the lotus" and I would associate this mantra primarily with Buddhism. The mantra OM Mani Padme Hum can be found on Tibetan prayer wheels and prayer flags and inscribed on stones in the landscape.
Given this mantra is so ancient there are numerous interpretations of it's meaning, but I like this one I found on Wikipedia:
According to the 14th Dalai Lama
"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 of the middle way 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, "On the meaning of: OM MANI PADME HUM"
I also like this interpretation, also found on Wikipedia.
