Dhammapada · 18.16

Yassa cetaṃ samucchinnaṃ, mūlaghaccaṃ samūhataṃ;Sa ve divā vā rattiṃ vā, samādhiṃ adhigacchati.

Yassa cetam samucchinnam, mulaghaccam samuhatam; Sa ve diva va rattim va, samadhim adhigacchati.

He in whom this envy is cut off, destroyed at the root, fully uprooted — he by day or night attains concentration.
