There are indeed many different speeds in the process of the attainment of enlightenment. The difference in people’s capacity to understand the Buddha’s teachings exists only in the area encompassed by “this shore” (shigan), the world of birth and death. But people become buddhas equally when they reach “that shore” (higan), the realm of nirvana. Therefore, there is no essential difference in their capacity to understand the Buddha’s teachings. This is the teaching of mirai-ki’itsu, “man’s capacity to understand the Buddha’s teachings is one in the future.” The Buddhist term fugen-daie, “all creatures universally see the great assembly of the Buddha surrounded by many other buddhas,” indicates the idea that the Buddha has the divine power to lead all living beings equally to the realm of nirvana in the future.

The expression “all the gods in the sky sang with exalted voices” means that all living beings in the sahā-world received inspiration from all the gods. Such an expression is not limited to Buddhism. The phrase “a voice was heard from heaven” appears in Christian writings, and the words “I hear heaven’s voice” are often used in the teachings of Confucius and Mencius. These words imply that people receive revelations from heaven, that is, that they perceive the truth of faith as if an inspiration had flashed across their minds.

What did all the living beings in the sahā-world receive by inspiration from the exalted voices of all the gods in the sky? They realized that in the sahā-world, Sakyamuni Buddha preached the teaching called the Lotus Flower of the Wonderful Law, the Law by which bodhisattvas are instructed and which the buddhas watch over and keep in mind. This is a true and peerless teaching, which causes all beings in the universe to live, bestows harmony on them, and brings about their peace of mind. This realization means that although the sahā-world is now a realm of suffering, it will surely become the most sacred land of the universe in the future, when all teaching and learning will be united into one in the Buddha’s teachings.
