At Savatthi. “Bhikkhus, I will teach you the fragile and the unfragile. Listen to that….

“And what, bhikkhus, is the fragile, and what the unfragile? Form is the fragile; its cessation, subsiding, passing away is the unfragile. Feeling is the fragile … Perception is the fragile …

Volitional formations are the fragile … Consciousness is the fragile; its cessation, subsiding, passing away is the unfragile.”
