Dhammapada · 25.6
Salābhaṃ nātimaññeyya, nāññesaṃ pihayaṃ care;Aññesaṃ pihayaṃ bhikkhu, samādhiṃ nādhigacchati.
Salabham natimanneyya, nannesam pihayam care; Annesam pihayam bhikkhu, samadhim nadhigacchati.
One should not despise one's own gain, nor go about envying others' gain. The bhikkhu who envies others does not attain concentration.
