WailingRuṇṇasutta

“Singing is regarded as wailing in the training of the Noble One.“Ruṇṇamidaṁ, bhikkhave, ariyassa vinaye yadidaṁ gītaṁ. Dancing is regarded as madness.Ummattakamidaṁ, bhikkhave, ariyassa vinaye yadidaṁ naccaṁ. Too much laughter, showing the teeth, is regarded as childish.Komārakamidaṁ, bhikkhave, ariyassa vinaye yadidaṁ ativelaṁ dantavidaṁsakahasitaṁ. So break off singing and dancing; and when you’re appropriately pleased, it’s enough to simply smile.”Tasmātiha, bhikkhave, setughāto gīte, setughāto nacce, alaṁ vo dhammappamoditānaṁ sataṁ sitaṁ sitamattāyā”ti.
