Itivuttaka 59

This was said by the Blessed One, said by the Arahant, so I have heard: “Endowed with three qualities, monks, a monk has passed beyond Māra’s domain and shines like the sun. Which three? There is the case where a monk is endowed with the aggregate of virtue of one beyond training [i.e., an Arahant], the aggregate of concentration of one beyond training, the aggregate of discernment of one beyond training. Endowed with these three qualities a monk has passed beyond Māra’s domain and shines like the sun.”
