[1590] On one occasion the Blessed One was dwelling among the Sakyans at Kapilavatthu, in Nigrodha's Park. Then Mahānāma the Sakyan approached the Blessed One; having approached, he paid homage to the Blessed One and sat down to one side. Sitting to one side, Mahānāma the Sakyan said this to the Blessed One: "In what way, venerable sir, is one a lay follower (upāsaka)?"
"Mahānāma, when one has gone for refuge to the Buddha, gone for refuge to the Dhamma, and gone for refuge to the Saṅgha — to that extent, Mahānāma, one is a lay follower."
