Theranāmasutta

[716] On one occasion the Blessed One was dwelling at Rājagaha, in the Bamboo Grove, the Squirrels' Feeding Ground. Now on that occasion a certain bhikkhu named Thera was one who dwelt alone and who spoke in praise of dwelling alone. Alone he entered the village for alms, alone he returned, alone he sat in seclusion, alone he undertook walking meditation. Then a number of bhikkhus approached the Blessed One; having approached, they paid homage to the Blessed One and sat down to one side. Sitting to one side, those bhikkhus said this to the Blessed One: "Here, venerable sir, a certain bhikkhu named Thera is one who dwells alone and who speaks in praise of dwelling alone."
