Mahapadanasutta 3.12.3

3.12.3

Seyyathāpi, bhante, nikkujjitaṃ vā ukkujjeyya, paṭicchannaṃ vā vivareyya, mūḷhassa vā maggaṃ ācikkheyya, andhakāre vā telapajjotaṃ dhāreyya: “cakkhumanto rūpāni dakkhantī”ti; evamevaṃ bhagavatā anekapariyāyena dhammo pakāsito.

As if he were righting the overturned, or revealing the hidden, or pointing out the path to the lost, or lighting a lamp in the dark so people with clear eyes can see what’s there, the Buddha has made the teaching clear in many ways.
