The External as Suffering

“Bhikkhus, forms are suffering. What is suffering is nonself. What is nonself should be seen as it really is with correct wisdom thus: ‘This is not mine, this I am not, this is not my self.’
“Sounds … Odours … Tastes … Tactile objects … Mental phenomena are suffering. What is suffering is nonself. What is nonself should be seen as it really is with correct wisdom thus: ‘This is not mine, this I am not, this is not my self.’
“Seeing thus … He understands: ‘… there is no more for this state of being.’”
