"Brooding on the objects of senses, attachment to them is formed; from attachment, desire; from desire, anger arises."
Modern explanation
In a moment of stillness, receive this: Anger is the last link in a chain that started with quiet rumination. Catch the chain earlier.
Practical application
Imagine the person you're upset with as a child. Notice if anything softens.
Reflection question
What would peace cost me — and am I willing to pay it?
