[1363] On one occasion the Blessed One was dwelling at Icchānaṅgala, in the Icchānaṅgala forest grove. There the Blessed One addressed the bhikkhus: "Bhikkhus, I wish to go into seclusion for three months. No one is to approach me except the one who brings the almsfood." "Yes, venerable sir," those bhikkhus replied to the Blessed One, and indeed no one approached the Blessed One except the one who brought the almsfood.
