Dhammapada · 10.16

Asso yathā bhadro kasāniviṭṭho, ātāpino saṃvegino bhavātha;Saddhāya sīlena ca vīriyena ca, samādhinā dhammavinicchayena ca;Sampannavijjācaraṇā patissatā, jahissatha dukkhamidaṃ anappakaṃ.

Asso yatha bhadro kasanivittho, atapino samvegino bhavatha; Saddhaya silena ca viriyena ca, samadhina dhammavinicchayena ca; Sampannavijjacarana patissata, jahissatha dukkhamidam anappakam.

Like a fine horse touched by the whip, be ardent and deeply moved. With faith, virtue, energy, concentration, and discernment of Dhamma — endowed with knowledge and conduct, mindful — you will abandon this great suffering.
