20. Dutiyasīsappacālakasikkhāpada

Tena samayena buddho bhagavā sāvatthiyaṁ viharati jetavane anāthapiṇḍikassa ārāme. Tena kho pana samayena chabbaggiyā bhikkhū sīsappacālakaṁ antaraghare nisīdanti sīsaṁ olambentā …pe….

Swaying the head Origin 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 swaying and tilting their heads while sitting in inhabited areas. …

“Na sīsappacālakaṁ antaraghare nisīdissāmīti sikkhā karaṇīyā”ti.

Final ruling

“‘I will not sway my head while sitting in inhabited areas,’ this is how you should train.”

Na sīsappacālakaṁ antaraghare nisīditabbaṁ. Sīsaṁ paggahetvā nisīditabbaṁ. Yo anādariyaṁ paṭicca sīsappacālakaṁ antaraghare nisīdati sīsaṁ olambento, āpatti dukkaṭassa.

One should not sway one’s head while sitting in an inhabited area; one should sit keeping one’s head straight. If a monk, out of disrespect, sways and tilts his head while sitting in an inhabited area, he commits an offense of wrong conduct.
