With Mahāmoggallāna

So I have heard.
At one time the Buddha was staying near Sāvatthī in Jeta’s Grove, Anāthapiṇḍika’s monastery.
Now at that time Venerable Mahāmoggallāna was sitting not far from the Buddha, cross-legged, with his body straight and mindfulness of the body well-established in himself.
The Buddha saw him meditating there.
Then, understanding this matter, on that occasion the Buddha expressed this heartfelt sentiment:
“With mindfulness of the body established,
restrained in the six fields of contact,
a mendicant always immersed in samādhi
would know quenching in themselves.”
