佛說佛名經 1.56

1.56

"What are called the three obstructions: the first is called the obstruction of kleśas; the second is named the karmic obstruction (karmāvaraṇa); the third is the obstruction of retribution. These three kinds of dharmas depend upon one another: because of kleśas, one produces evil karma; by reason of evil karma, one obtains bitter retribution. Therefore, disciple, today with a sincere mind, you should first perform kṣamā for the obstruction of kleśas.
