Brittle
At Sāvatthī. “Mendicants, I will teach you what is brittle and what is not brittle. Listen … And what is brittle? What is not brittle? Form is brittle, but its cessation, settling, and disappearance is not brittle. Feeling … perception … choices … consciousness is brittle, but its cessation, settling, and disappearance is not brittle.”
