We must not spare our voices in sharing with many others the supreme teaching [of Nam-myoho-renge-kyo]. Through such efforts, we help connect them to the Mystic Law, a cause for their eternal happiness. And we create a personal chronicle that brims with everlasting good fortune. As the Daishonin says, “Single-mindedly chant Nam-myoho-renge-kyo and urge others to do the same; that will remain as the only memory of your present life in this human world” (WND-1, 64).
