佛頂尊勝陀羅尼經教跡義記 1.109

1.109

述曰：第七、三業清淨也。若人憶念此陀羅尼，所有十惡之業皆悉消滅，所以三業清淨也。

Commentary: Seventh, the three karmic activities become purified. If someone remembers this dhāraṇī, all of their karmas of the ten unwholesome actions will be entirely eradicated; therefore, the three karmic activities are purified.
