Important Matters, p 38-39Hear me roar like the lion!
“The Buddha is the unexcelled King of the Dharma. Once we chant what he preached with his golden lips, the spiritual phrases of the sacred teachings, those words will become a Dharma-wheel that travels throughout the earth. The yakshas chant to the sky as an offering to the Four Heavenly Kings. After the Heavenly Kings hear it, they then pass it on until it reaches the King ofthe Brahma Heaven. This chanting spreads out to the dead and to the living. The dragon-gods are as pleased as when people listen to the speech ofa king. Who would not praise it? The merit of chanting is like this.”
Wu-chin, Goho-ron (Treatise on Protecting the Dharma), Shute Hoyo Shiki, page 393
Even though our ears are not fine-tuned and so are unable to hear many frequencies, our voices are heard and cause the universe to move. We can have a voice of love or of hate, and then what we hear in return, what we experience is in accord with our voice. Think how the universe is moved when we recite the words of the Buddha. Even our small voice reaches the heavens.
