佛說佛名經 1.46

1.46

「弟子！今日所以懺悔者，正言無始已來在凡夫地，莫問貴賤罪自無量，或因三業而生罪，或從六根而起過，或以內心自邪思惟，或籍外境起於染著，如是乃至十惡增長，八萬四千諸塵勞門。然其罪相雖復無量，大而為語不出有三。何等為三？一者、煩惱障；二者、是業障；三者、是果報障；此三種法能障聖道，及以人天勝妙好事。是故經中目為三障，所以諸佛菩薩教作方便懺悔，除滅此三障者，則六根十惡乃至八萬四千諸塵勞門皆悉清淨。

"The reason we disciples perform kṣamā today is precisely because, having been in the stage of ordinary mortals since anādikāla, whether noble or lowly, our sins are naturally immeasurable. Sins have arisen either due to the three modes of karma, or faults have originated through the six sense faculties; or through improper thinking in one's own mind, or by generating attachment relying on external objects. In this way, they have developed into the ten unwholesome actions and even the eighty-four thousand gates of defilement. Yet although the aspects of sin are immeasurable, broadly speaking they do not exceed three. What are the three? The first is the hindrance of kleśa; the second is the karmāvaraṇa; the third is the hindrance of retribution. These three kinds of phenomena can obstruct the noble path as well as the supreme and wondrous benefits of devas and humans. Therefore, in the sūtras they are designated as the 'three hindrances'. Hence, the Buddhas and Bodhisattvas teach skillful means of kṣamā; if one eliminates these three hindrances, then the six sense faculties, the ten unwholesome actions, and even the eighty-four thousand gates of defilement will all become completely purified.
