The Great Mandala shows all the sentient beings of the ten worlds illuminated by the Odaimoku. The buddhas of past, present, and future are included in this. Shakyamuni Buddha represents the Buddhas of the present, while Many Treasures Tathagata represents all the Buddhas of the past, and the sentient beings of the other nine worlds are the Buddhas of the future. This shows that all the Buddhas of past, present, and future are unified with the Odaimoku.
