Impermanence (2nd)
At Sāvatthī. “Mendicants, form is impermanent. What’s impermanent is suffering. What’s suffering is not-self. And what’s not-self should be truly seen with right understanding like this: ‘This is not mine, I am not this, this is not my self.’ Feeling is impermanent … Perception is impermanent … Choices are impermanent … Consciousness is impermanent. What’s impermanent is suffering. What’s suffering is not-self. And what’s not-self should be truly seen with right understanding like this: ‘This is not mine, I am not this, this is not my self.’
