Because of the ray of light the Buddha emitted those present in the congregation were able to see far into the past. They were able to see Buddhas, and stupas of those Buddhas. In various places in the Lotus Sutra, the Buddha reveals the past causes of a variety of people so they can know the causes made that enabled them to become Buddhas.
We may think that these are not things we can accomplish, yet through our daily practice of the Odaimoku and faith in the Lotus Sutra, we are able to reveal the historical truth of the Bodhisattvas who arose from beneath the earth. We can, by chanting Odaimoku, manifest the life of these great Bodhisattvas and reveal our infinite connection with the Eternal Buddha.
