Sanzo's Mantra

The prayer, or manta, that Sanzo recites to activate his Sutra is:

オン マ ン　ハツ メイ ウン (on ma ni hatsu mei un) or in Chinese characters: 唵　嘛　呢　叭　咪　吽.

It comes from the prayer: "Om mani padme hum", a Sanskirt mantra from Lamaism (A Tibetan Buddhism) meaning: "The Jewel in the Lotus".

It's a prayer asking Kanzeon Bosatsu to deliver the speaker a peaceful death and paradise.
