KETOKHILA-SUTTA –
BARRENNESS AND BONDAGE
19. ‘And further, O Bhikkhus, when a brother is not angry with his fellow-disciples, is not discontented with them, is not excited against them, is not barren towards them, the mind of the brother, O Bhikkhus, who is thus not angry with his fellow-disciples, not discontented with them, not excited against them, not barren towards them, does incline toward zeal, exertion, perseverance, and struggle.
But whosesoever mind inclineth towards zeal, exertion, perseverance, and struggle, he has become free from this fifth spiritual barrenness.’
