Om Mani Padme Hum

Om Mani Padme Hum is said to be the most powerful mantra, holding all of the teachings of Buddha. To the right is an image of how the mantra would look if it were written in the tibetan alphabet.  From left to right the syllables are OM (Ohm), MA (Mah), NI (Nee), PAD (Pahd), ME (May), HUM (Hum).  The following video is a powerful Om Mani Padme Hum mantra gifted by the thousand buddhas

"There is not a single aspect of the eighty-four thousand sections of the Buddha's teachings which is not contained in Avalokiteshvara's six syllable mantra "Om Mani Padme Hum", and as such the qualities of the "mani" are praised again and again in the Sutras and Tantras.... Whether happy or sad, if we take the "mani" as our refuge, Chenrezig will never forsake us, spontaneous devotion will arise in our minds and the Great Vehicle will effortlessly be realized."
