[171] Then a certain bhikkhu, not long after the Blessed One had departed, approached the Venerable Ānanda; having approached, he said this to the Venerable Ānanda: "Come, friend Ānanda, the Blessed One, having set his lodging in order himself, having taken his bowl and robe, without informing his attendants, without taking leave of the Saṅgha of bhikkhus, has set out on a wandering tour alone, without a companion."
"Friend, when the Blessed One, having set his lodging in order himself, having taken his bowl and robe, without informing his attendants, without taking leave of the Saṅgha of bhikkhus, sets out on a wandering tour alone, without a companion, on that occasion the Blessed One wishes to dwell alone; on that occasion the Blessed One is not to be followed by anyone."
