Vinaya — Regras dos Monges (Bhikkhu Vibhaṅga) — Laughing loudly

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 were laughing loudly while walking in inhabited areas. …

2Final ruling
“‘I will not laugh loudly while walking in inhabited areas,’ this is how you should train.”

3One should not laugh loudly while walking in an inhabited area. If a monk, out of disrespect, laughs loudly while walking in an inhabited area, he commits an offense of wrong conduct.

4Non-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 merely smiles when something is funny; if there is an emergency; if he is insane; if he is the first offender.

5The first training rule is finished.
