"Bhikkhus, I will teach you the disintegrating (pabhaṅgu) and the non-disintegrating (appabhaṅgu). Listen to it. And what, bhikkhus, is the disintegrating, and what the non-disintegrating? Form (rūpa), bhikkhus, is disintegrating; its cessation, subsiding, and passing away — this is the non-disintegrating. Feeling (vedanā) is disintegrating; its cessation, subsiding, and passing away — this is the non-disintegrating. Perception is disintegrating. … Volitional formations are disintegrating; their cessation, subsiding, and passing away — this is the non-disintegrating. Consciousness is disintegrating; its cessation, subsiding, and passing away — this is the non-disintegrating."
The Burden Chapter (Bhāravagga), the third.
