Dhammapada · 24.20

Sabbābhibhū sabbavidūhamasmi, sabbesu dhammesu anūpalitto;Sabbañjaho taṇhakkhaye vimutto, sayaṃ abhiññāya kamuddiseyyaṃ.

Sabbabhibhu sabbavidu-hamasmi, sabbesu dhammesu anupalitto; Sabbanjaho tanhakkhaye vimutto, sayam abhinnaya kamuddiseyyam.

All-conqueror, all-knower am I. In all dhammas, untainted. All-abandoning, freed in the destruction of craving. Having known by myself — whom should I call my teacher?
