And then that mendicant approved and agreed with what the Buddha said. He got up from his seat, bowed and respectfully circled the Buddha, keeping him on his right, before leaving. Then that mendicant, living alone, withdrawn, diligent, keen, and resolute, soon realized the supreme culmination of the spiritual path in this very life. He lived having achieved with his own insight the goal for which gentlemen rightly go forth from the lay life to homelessness. He understood: “Rebirth is ended; the spiritual journey has been completed; what had to be done has been done; there is nothing further for this place.” And that mendicant became one of the perfected.

At one time the Buddha was staying in the land of the Kosalans near the brahmin village of Sālā. There the Buddha addressed the mendicants:

“Mendicants, those mendicants who are junior—recently gone forth, newly come to this teaching and training—should be encouraged, supported, and established by you in the four kinds of mindfulness meditation. What four? Please, reverends, meditate observing an aspect of the body—keen, aware, at one, with minds that are clear, immersed and unified in samādhi, so as to truly know the body. Meditate observing an aspect of feelings—keen, aware, at one, with minds that are clear, immersed and unified in samādhi, so as to truly know feelings. Meditate observing an aspect of the mind—keen, aware, at one, with minds that are clear, immersed and unified in samādhi, so as to truly know the mind. Meditate observing an aspect of principles—keen, aware, at one, with minds that are clear, immersed and unified in samādhi, so as to truly know principles.
