Vinaya — Regras dos Monges (Bhikkhu Vibhaṅga) — Covering the head

1Origin story
At one time the Buddha was staying at Sāvatthī in the Jeta Grove, Anāthapiṇḍika’s Monastery. At that time the monks from the group of six gave teachings to people with covered heads. …

2Final ruling
“‘I will not give a teaching to anyone with a covered head who is not sick,’ this is how you should train.”

3Definitions
With a covered head:

4the upper robe covering the head is what is meant.

5One should not give a teaching to anyone with a covered head who is not sick. If a monk, out of disrespect, gives a teaching to someone with a covered head who is not sick, he commits an offense of wrong conduct.

6Non-offenses
There is no offense: if it is unintentional; if he is not mindful; if he does not know; if he is sick; if he teaches the person after having them uncover their head; if there is an emergency; if he is insane; if he is the first offender.
