“Monks, don’t think bad, unwholesome thoughts, such as worldly thoughts, angry thoughts, and violent thoughts. Why? Because those thoughts aren’t beneficial or relevant to the basics of the spiritual life. They don’t lead to letting go, dispassion, cessation, peace, insight, enlightenment, and Nibbāna.
“When you think, you should think: ‘This is suffering’ … ‘This is the origin of suffering’ … ‘This is the end of suffering’ … ‘This is the path that leads to the end of suffering’. Why? Because those thoughts are beneficial and relevant to the basics of the spiritual life. They lead to letting go, dispassion, cessation, peace, insight, enlightenment, and Nibbāna.
“Therefore, monks, you should make an effort to understand: ‘This is suffering.’ You should make an effort to understand: ‘This is the origin of suffering.’ You should make an effort to understand: ‘This is the end of suffering.’ You should make an effort to understand: ‘This is the path that leads to the end of suffering.’”
