A monk asked the Buddha: “What is one thing a monk can do to find insight?”
The Buddha replied: “That one thing is to clear away your confusion about the nature of the world.”
The monk: “But how can I do that?”
The Buddha: “Know this: there is nothing in this world worthy of your desire. When you truly, directly know that nothing is worth your attachments, you comprehend everything there is to know. You see the world differently. You see that your senses are not your self. Your pleasure, your pain, all experiences are not your self. Your thinking mind is not your self.
“When you can truly, directly know this, insight will arise.”
from Samyutta Nikaya 35.80
