From the eternal past, 500 (million) dust particle kalpa ago, this Sahā World has been the territory of Śākyamuni Buddha, Lord Preacher of the Lotus Sūtra. The earth, sky, mountains, and oceans, even trees and plants do not belong to other Buddhas. Moreover, all living beings are the children of Śākyamuni Buddha. At the beginning of the (period) of creation, one of the Brahma kings descended from the heavens and gave birth to the living beings of the six lower realms thus becoming the parent of all living beings. In the same way Śākyamuni Buddha is also the parent of all living beings. Lord Preacher Śākyamuni Buddha is the excellent teacher who shows all living beings in this country the right way. He teaches us justice such as our debt of gratitude to our parents and judgment of good and evil.
