[925] On one occasion the Blessed One was dwelling at Sāvatthī, in the Jeta Grove, in Anāthapiṇḍika's Park. Now on that occasion the Blessed One had gone for the day's abiding and was in seclusion. Then Sakka, lord of the devas, and Brahmā Sahampati approached the Blessed One; having approached, they stood each leaning against a doorpost.
