[T]he Buddhas in all the worlds throughout the universe have attained Buddhahood by making the “jiga-ge” verse their True Teacher. The “jiga-ge” is, therefore, like the parents of all beings in the world. Accordingly, those who uphold the “Life Span of the Buddha” chapter in the Lotus Sūtra can be said to be the inheritors of the life of Buddhas in the world. Is there any Buddha who would abandon the upholders of the Lotus Sūtra, through which He attained enlightenment? Should any Buddha abandon them, is He not in turn abandoning Himself. We infer from this that he who stands against a woman who has 3,000 children as powerful as Sakanoue Tamuramaro or Fujiwara Toshihito, will fight against 3,000 military commanders. Likewise, standing against he who upholds the “jiga-ge” verse of the Lotus Sūtra fights against the various Buddhas in the past, present, and future.
