Japanese commentary: ko^ben's 高辯 Explanation of Passages in the Light Mantra of the Great Consecration of the Infallible Lasso Vairocana When you recite this mantra, visualize a moon disc in your heart, with a golden Sanskrit seed syllable AH on it. This syllable AH radiates light and illuminates on all sentient beings. Anyone in contact with this light will be liberated from suffering and receive joy. It is as good as receiving a jewel, a lotus, a rebirth and illumination, where liberation is instantaneous and all vows are fulfilled.
The mantra should be chanted 3, 7, or 21 times per day.
