Of the 25 transmitters of the Buddhist dharma, all except the Buddha are men of temporary manifestation dispatched by the Buddha to lead living beings. Āryadeva, the 14th of the 25 transmitters, was killed by a non-Buddhist, and Venerable Simha, the 25th transmitter, was beheaded by King Dammira. Many others such as Buddhamitra and Bodhisattva Nāgārjuna encountered various difficulties. On the other hand, some were firmly supported by the rulers and were able to spread the dharma without encountering difficulties. Why is it that some transmitters were persecuted while others were not? I believe it is because there exist good and wicked countries in the world and aggressive and persuasive means of spreading a religion. This was true even during the Ages of the True Dharma and the Semblance Dharma. It was also true even in India, the central land of the Buddhist dharma. All the more so in Japan, a remote country land, at the beginning of the Latter Age of Degeneration. It has been expected from the beginning that I would encounter great difficulties when I tried to spread the teaching of the Lotus Sutra. I simply waited for them to arise.
