三彌勒經疏 1.80

1.80

經曰「爾時此宮」以下，第二辨一大神造內法堂。此中三：初大神發願、次所願果遂、後諸天覩勝發願往生。是初也。牢度跋提，此云惡主，以治惡主故。謂夜叉，天相似。冥潛難測名神，神中最勝曰大也，由菩薩增上力現。一大神者，表無漏智能起妙土。

From the sūtra passage stating, "At that time, this palace…" downward is the second [part], explaining that a great spirit created the inner Dharma hall. This contains three parts: first, the great spirit makes a vow; second, the fulfillment of what was vowed; and third, the devas, seeing the excellence, make vows to be reborn there. This is the first.

*Raudrabhadra* translates here as "Terrible Master" (or "Evil Master"), because he subdues terrible masters. That is, a yakṣa is similar to a deva. That which is hidden, subtle, and difficult to fathom is called a "spirit" (shen), and the most supreme among spirits is called "great." It is manifested through the Bodhisattva's sovereign power. A "single great spirit" symbolizes that untainted wisdom is capable of producing a wondrous land.
