"Why is this? A bodhisattva acquires a buddha-land according to the sentient beings he transforms." This second clarifies the sequential explanation of the four clauses, which has four parts. This first explains the reason for the different expansiveness or narrowness of buddha-lands. Sengzhao says: "Below this, it explains why sentient beings are themselves the buddha-land. The buddha-land is simply the shadow and echo of sentient beings. When a form is tall, its shadow is long; when a form is short, its shadow is brief. Do the sun and moon make it so? It is simply the nature of the form itself. Therefore, according to the greater or lesser number of sentient beings transformed, he acquires a buddha-land of greater or lesser extent. Hence, a buddha-land may take the four continents, a trichiliocosm, or sands of the Ganges as one realm."
