“Do not overrate what you have received, nor envy others. He who envies others does not obtain peace of mind.”
Dhammapada Verses 365 and 366
Vipakkhasevaka Bhikkhu Vatthu
Salabham natimanneyya
na’ nnesam pihayam care
annesam pihayam bhikkhu
samadhim nadhigacchati.
Appalabhopi ce bhikkhu
salabham nati mannati
tam ve deva pasamasanti
suddhajivim atanditam.
Verse 365: One should not despise what one has received (by proper means), nor should one envy others their gains. The bhikkhu who envies others cannot attain Concentration (Samadhi).
Verse 366: Though he receives only a little, if a bhikkhu does not despise what he has received (by proper means), the devas will surely praise him who leads a pure life and is not slothful.
