Observation of the natural breath anchors mindfulness of the body. Watching inhalation and exhalation trains continuous, non-reactive attention.
The text directs attention to bodily sensations as they arise and pass. Watching feeling without craving or aversion reveals impermanence directly.
By observing phenomena without reacting, the practitioner weakens the habit of craving and aversion. Non-identification with experience is the mechanism of freedom the sutta teaches.
Liberation comes from personally observing mind and body, not from doctrine. The path is empirical and introspective rather than devotional.
Sustained observation reveals the three marks of all phenomena. Seeing arising and passing firsthand loosens attachment to a fixed self.
