Dhamma Verses (Dhammapada, KN 2)

8: The Chapter about the Thousands – 106
The one who conquers self cannot be defeated
A brahmin admitted to earning his living through gambling,
and the Buddha explained that gains in this way are no true
gains, but those who overcame themselves are truly victorious,
and then he gave him this teaching.
104-105. Attā have jitaṁ seyyo yā cāyaṁ itarā pajā,
attadantassa posassa, niccaṁ saññatacārino,
neva devo na gandhabbo, na Māro saha Brahmunā,
jitaṁ apajitaṁ kay i rā tathārūpassa jantuno.
Conquest over self is better
than that over other people,
for the one who conquers himself,
who lives constantly well-restrained,
neither gods, nor gandhabbas, nor
Māra together with Brahmās,
can turn conquest into defeat
for a person who is like this.
