He introduced this remarkable Six-Syllable Mantra to the assembly and said, "This is the most beneficial mantra." The meaning of this mantra is:
Om, it is composed of three letters, A, U, M, these symbolize the pure exalted body, speech and mind of a Buddha and Bodhisattva.
Mani, meaning precious jewel, symbolizes the method, the great compassion and loving kindness. Just as a precious jewel is capable of fulfilling the outer needs of sentient beings, similarly the loving kindness and compassion are capable of fulfilling the inner needs of sentient beings.
Padme, meaning lotus, symbolizes wisdom. Just as lotus are grown from mud but is not polluted with mud, similarly with this analogy, wisdom "The Supreme Knowledge" are grown from an ordinary mind but are not polluted with ordinary thoughts.
Hum, indicates union. The union of method and wisdom that leads to pure exalted Body, Speech and Mind of enlightened beings.
