Those mendicants who are perfected—who have ended the defilements … for them, the five hindrances are cut off at the root … and unable to arise in the future. And here’s another way to understand how the meditation of a trainee and a realized one are different.

At one time the Buddha was staying in a forest near Icchānaṅgala. There he addressed the mendicants, ‘Mendicants, I wish to go on retreat for three months. No-one should approach me, except the one who brings my almsfood.’ ‘Yes, sir,’ replied those mendicants. And no-one approached him, except the one who brought the almsfood.
