When Śākyamuni Buddha, the Buddha of Many Treasures, and many other Buddhas and bodhisattvas from all over the Universe gathered at the assembly up in the sky above Mt. Sacred Eagle, what Śākyamuni Buddha and the Buddha of Many Treasures agreed upon was solely for the sake of perpetually spreading the Lotus Sūtra in the Latter Age of Degeneration. When the Buddha of Many Treasures who had already been inside the Stupa shared his seat with Śākyamuni Buddha, what was decided by the two Buddhas as generals standing under the flag of Myōhō Renge Kyō was nothing but the truth. It was a meeting to help us living beings achieve Buddhahood. Although I was not at the scene, I have no doubt about it when I read the sūtra. However, I may have been there, but I don’t remember it simply because I am an ordinary man. And yet I can see clearly in the present time that I am a practicer of the Lotus Sūtra. Moreover, it is determined that I will surely visit the practicing place of the Buddha in the future. Considering the past according to these things, I may have been at the assembly up in the sky because the past, present, and future are not separated from one another.
