觀彌勒上生兜率天經贊 2.33

2.33

贊曰：此有二嚴。八地相土皆得自在，故能現起閻浮金光，此於諸金最為第一。近閻浮樹水下而有，色蔽諸光，故偏舉此。九地成熟四無礙解，化利眾生出生善根，感寶女故。

The commentary says: Here there are two adornments. On the eighth ground, one attains mastery over both characteristics and lands, and can thus manifest the golden light of Jāmbūnada [gold]; this is the foremost among all golds. It exists beneath the waters near the jambu tree, and its colour eclipses all other lights; therefore this alone is cited. On the ninth ground, one brings to maturity the four unhindered understandings, transforms and benefits sentient beings, and brings forth wholesome roots; hence it karmically brings about the precious maidens.
