三彌勒經疏 1.101

1.101

經曰「時諸人天」以下，第七天人供養。妙塔者，昔云兜婆，此云塔，訛語。今窣堵婆，此云積聚也。

From the text of the sūtra where it says, "At that time all humans and devas" onwards, this is the seventh [section], [explaining] the offerings made by devas and humans. "Wondrous tower": formerly this was called a *toupo*, which is translated here as "tower," a corrupt word. Nowadays it is *stūpa*, which is translated here as "accumulation."
