After all, those with capacity to understand and have full faith in Buddhism who had the luck of listening to Śākyamuni Buddha preach the Lotus Sūtra in India must have accumulated a great deal of merit in their past lives. Moreover, they were fortunate to have been assisted and guided by the Lord Śākyamuni Buddha, the Buddha of Many Treasures, who had come to attest to the truth of Śākyamuni’s words, various Buddhas in manifestation who had come from all over the universe, numerous bodhisattvas who had sprung up from underground, and such distinguished disciples of Śākyamuni Buddha as Mañjuśrī and Maitreya. Nevertheless, there were some who were not converted to the Lotus Sūtra. This is the reason why those self-conceited, as many as 5,000, moved out when the Buddha was about to start preaching (chapter 2, “Expedients”), and why some men and gods were transferred to other worlds (chapter 11, “The Appearance of the Stupa of Treasures”). It was so even while Śākyamuni Buddha was alive. How much more difficult is it to believe in the Lotus Sūtra in the Ages of the True Dharma and Semblance Dharma after the death of Śākyamuni Buddha, not to say in the beginning of the Latter Age of Degeneration? If you could easily believe in the sūtra, it would mean that the sūtra is not the True Dharma.
