The mantra Om
Mani Pädme Hum is easy to say yet quite powerful, because it
contains the essence of the entire teaching. When you say 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.
So in this way
recitation of the mantra helps achieve perfection in the six
practices from generosity to wisdom. The path of these six
perfections is the path walked by all the Buddhas of the three
times. What could then be more meaningful than to say the mantra
and accomplish the six perfections?
