This was said by the Blessed One, said by the Arahant, so I have heard: “Monks, ignorance1 precedes the arrival of unskillful qualities; lack of shame & lack of compunction2 follow after. Clear knowing precedes the arrival of skillful qualities; shame & compunction follow after.”
Any bad destinations in this world, in the next, are rooted in ignorance–all– accumulations of desire & greed. And when a person of evil desires lacks shame & respect, evil comes from that, and by that he goes to deprivation. So cleansing away ignorance, desire, & greed, a monk giving rise to clear knowing would abandon all bad destinations.
1. Ignorance (avijjā) means ignorance of stress, its origination, its cessation, and the way leading to its cessation.
2. Shame (hiri) means a healthy sense of shame–derived from self-esteem–at the idea of doing evil. Compunction (ottappa) means fear of the consequences of doing evil.
