Whatever else it is, the great Stupa in this story is a literary device providing a reason for assembling all of the buddhas from all directions. This Stupa springing out of the earth from the past could be material from a dream, or from a rich imagination. But it can also be said that Abundant Treasures Buddha symbolizes the truth, the Dharma that does not change and is a kind of ground or basis for all teaching of the Dharma. In this way, Shakyamuni Buddha can symbolize the teacher of the Dharma. And the two buddhas sitting together on a single seat would indicate both that the teacher is to be respected as much as the truth itself, and the opposite, namely, that however devoted we may be to Shakyamuni Buddha for teaching, we should remember that our devotion should be based on his teaching the truth.
