Thus have I heard - At one time, the Blessed One was dwelling in Sāvatthi, in Jeta's Grove, Anāthapiṇḍika's park. Now, at that time, the venerable Mahāmoggallāna was sitting not far from the Blessed One, having folded his legs in a cross-legged sitting position, aligning his body upright, and with mindfulness immersed in the body, well-established internally.

The Blessed One saw the venerable Mahāmoggallāna sitting not far away, having folded his legs in a cross-legged sitting position, aligning his body upright, and with mindfulness immersed in the body, well-established internally.

Then, understanding the significance of this, the Blessed One at that time expressed this inspired utterance:

"Established in the mindfulness immersed in the body, restrained in the six sense bases; A bhikkhu who is continuously collected, can realize Nibbāna for himself."
