The verse in the image comes from a version of the Dharmapada that belonged to the Dharmaguptaka school of early Buddhism. An equivalent verse is also found in the Pāli Canon, though not in the Dhammapada. (It’s at Theragāthā 398). Translation from Richard Salomon, 2018. ‘The Buddhist Literature of Ancient Gandhāra: an Introduction with Selected Translations.’ Somerville, MA: Wisdom Books, p. 193. The image of the musician comes from www.riaa.com.
