金光明最勝王經疏 3.537

3.537

經　「如人被火燒頭燒衣，救令速滅；火若未滅，心不得安。若人犯罪亦復如是，即應懺悔令速除滅。」

Sūtra: "Just as a person whose head or clothes are set on fire strives to extinguish it quickly, and as long as the fire is not extinguished their heart cannot be at ease; if a person commits an offense it is also like this: they should immediately confess and cause it to be quickly eliminated."
