[64] It is possible, friend, that some bhikkhu here might have a wish arise thus: 'Oh, may it be I alone who teaches the Dhamma to the bhikkhus who have come to the monastery; may no other bhikkhu teach the Dhamma to the bhikkhus who have come to the monastery.' But it is possible, friend, that some other bhikkhu teaches the Dhamma to the bhikkhus who have come to the monastery, and that bhikkhu does not teach the Dhamma to the bhikkhus who have come to the monastery. Thinking, 'Another bhikkhu is teaching the Dhamma to the bhikkhus who have come to the monastery; I am not teaching the Dhamma to the bhikkhus who have come to the monastery,' he becomes angry and displeased. And that anger, friend, and that displeasure — both of these are a blemish (aṅgaṇa).
