說無垢稱經疏 2.227

2.227

贊曰：此釋所由。諸修行者自心嚴淨，外感有情器土亦淨。自心不淨，何得淨地？所以菩薩自心清淨，五蘊假者有情亦淨；內心既淨，外感有情及器亦淨。《佛地經》言「最極自在，淨識為相。」故識淨時佛土便淨。上來但說有情為土，本所化故。不說器界，有情土淨器界自淨，不說自成。

Commentary: This explains the reason. When practitioners adorn and purify their own minds, externally they attract sentient beings and a vessel land that are also pure. If one's own mind is not pure, how could one attain a pure land? Therefore, when a bodhisattva's own mind is pure, the sentient beings who are nominal entities of the five aggregates are also pure; once the inner mind is pure, externally it attracts sentient beings and the vessel that are also pure. The Buddhabhūmi-sūtra says: "Utterly sovereign, pure consciousness is its characteristic." Therefore, when consciousness is pure, the Buddha-land is pure. Heretofore, sentient beings have only been spoken of as the land because they are originally what is transformed. The vessel world was not mentioned because when the land of sentient beings is pure, the vessel world is naturally pure; without being spoken of, it is established on its own.
