The Lotus Sūtra is like the moon. The rays of light emitted by stars reach the distance of half a mile, 1, 10, or 20 miles at the most whereas the rays of the moon light reach as far as 1,000 miles or so. Even if all stars in the four continents and all the worlds throughout the universe, 100, 1,000, 10,000, 1,000,000 in number, are put together, they are not comparable to the moon in brightness. It goes without saying that one star can never be compared to the moon in brightness. Likewise, all the sūtras such as the Flower Garland Sūtra, the Āgama sūtras, the Hōdō sūtras, the Wisdom Sūtra, the Nirvana Sūtra, the Great Sun Buddha Sūtra, and the Sūtra of Meditation on the Buddha of Infinite Life put together, do not amount to one character of the Lotus Sūtra.
