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 Sāriputta was sitting not far from the Blessed One, having folded his legs in a cross-legged sitting position, aligning his body upright, and having set up mindfulness at the fore.

The Blessed One saw the venerable Sāriputta sitting not far away, having folded his legs in a cross-legged sitting position, aligning his body upright, and having set up mindfulness at the fore.

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

"Just as a rocky mountain, is unshakable and firmly grounded; In the same way, with the complete ending of delusion, a bhikkhu does not shake like the mountain."
