Mantra
Mantras are invocations to buddhas...prayers, or a combination of
these. Tantric practitioners repeat them in order to forge karmic
connections between themselves and meditational deities and to effect
cognitive restructuring through internalizing the divine attributes that
the mantra represents.
A person who wishes to develop greater compassion, for instance, might
recite the mantra of Avalokitesvara, who embodies this quality: om mani
padme hum...[a] mantra [that] is well known to Tibetans. It represents
for them the perfect compassion of Avalokitesvara, who they believe has
taken a special interest in the spiritual welfare of the Tibetan people.
He epitomizes universal compassion that is unsullied by any trace of
negative emotions or mental afflictions.
Among ordinary beings there are, of course, many acts of
compassion, but these are generally tinged by self-interest, pride, or
desire for recognition. Avalokitesvara' s compassion, by contrast, is
completely free from all afflictions and is so vast that it encompasses
all sentient beings without exception and without distinction. People
who wish to develop such a perspective recite Avalokitesvara' s mantra
over and over, meditating on its significance, and in so doing they try
to restructure their minds in accordance with the cultivation of his
exalted qualities. According to the Dalai Lama,
mani... symbolizes the factors of method--the altruistic intention
to become enlightened, compassion, and love. Just as a jewel is capable
of removing poverty, so the altruistic mind of enlightenment is capable
of removing the poverty, or difficulties, of cyclic existence and of
solitary peace....
The two syllables, padme...symbolize wisdom. Just as a lotus grows forth
from mud but is not sullied by the faults of mud, so wisdom is capable
of putting you in a situation of non-contradiction whereas there would
be contradiction if you did not have 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 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.
