Rice, spiked millet, pulse, wheat, glutinous millet, and common millet. These six grains are those which men eat. The horse, the ox, the sheep, the fowl, the dog, the pig. These six animals are those which men keep. We speak of joy, of anger, we speak of pity, of fear, of love, of hate, and of desire. These are the seven passions. The gourd, earthenware, skin, wood, stone, metal, silk, and bamboo, yield the eight musical sounds.
