At one time the Buddha was wandering in the land of the Kosalans together with a large Saṅgha of mendicants when he arrived at a village of the Kosalan brahmins named Opāsāda.
Now at that time the brahmin Caṅkī was living in Opāsāda. It was a crown property given by King Pasenadi of Kosala, teeming with living creatures, full of hay, wood, water, and grain, a royal park endowed to a brahmin.
