ud.6.7 Udana
With Subhūti
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 Subhūti was sitting not far from the Buddha, cross-legged, with his body straight, having attained the immersion free of placing the mind.
The Buddha saw him meditating there.
Then, understanding this matter, on that occasion the Buddha expressed this heartfelt sentiment:
“In whom mental vibrations are cleared away,
internally clipped off entirely,
perceiving the formless, beyond attachments,
having overcome the four yokes, they are not born again.”
