The king of Āḷavi who, while hunting, strayed into the shadow of a banyan tree inhabited by a man-eating yakkha and secured his release only by promising to supply the spirit with a human victim and a bowl of food at regular intervals.

The man-eating spirit whose demand for a periodic human sacrifice was ultimately extended even to the king’s own son, until the Buddha entered its dwelling in its absence and won it over through teaching.

A name given to the monks of Āḷavī, whose over-zealous building activities and tree-felling once so provoked a tree-spirit and the local populace that the Buddha had to restrain them and teach the Uraga Sutta.
