Kaccānasutta

ud7.8:1.1 So I have heard.

ud7.8:1.2 At one time the Buddha was staying near Sāvatthī in Jeta’s Grove, Anāthapiṇḍika’s monastery.

ud7.8:1.3 Now at that time Venerable Mahākaccāna was sitting not far from the Buddha, cross-legged, with his body straight and mindfulness of the body well-established internally on the present.
