At one time the Buddha was wandering in the land of the Mallas together with a large Saṅgha of mendicants when he arrived at a brahmin town of the Mallas named Thūṇa.
“It seems the ascetic Gotama—a Sakyan, gone forth from a Sakyan family—while wandering in the land of the Mallas has arrived at Thūṇa, together with a large Saṅgha of mendicants.”
