Dhovana Sutta
On the difference between the purification (dhovana) practised by people of the southern countries and that practised by the Noble Ones (ariya) (A.v.216 f).
The Commentary explains (AA.ii.858) that in the south people do not burn their dead, but bury them. When the corpse has decayed, they remove the bones, wash them, arrange them in due order, and, on feast days, offer to them flowers and incense and lamentations.
