Taught at Jetavana. Ānanda is instructed as to how concentration on breathing (ānāpānasati) leads to the four foundations of mindfulness (satipaṭṭhāna) and how these, in turn, bring to completion the seven factors of enlightenment (bojjhaṅga). These last lead to complete knowledge and release (vijjāvimutti). The methods of their development are explained in detail. S.v.328-33.
