The Power of Thought — The Dhammapada

You are what you think. That is how this chapter starts. If you think evil thoughts and act on them, pain follows you like a wheel follows an ox. If you think pure thoughts, happiness follows like a shadow that stays.

The chapter shows pairs of opposite choices. People who keep replaying "he hurt me, he cheated me" never stop hating. People who drop that script can let hate die. Only love ends hate, not more hate. People who know life ends stop wasting time on small fights.

Then Buddha talks about self-control. Someone who chases every pleasure with loose habits gets knocked down by Mara like wind blowing over a weak tree. Someone who eats less, stays steady, and controls the senses stands like a rocky mountain. Wearing a monk's yellow robe means nothing if your heart is still dirty inside.

Bad thoughts are like rain breaking through a bad roof. A guarded mind is like a strong roof that holds. Evil people mourn in this life and the next when they see what they did. Good people rejoice at their own clean actions. Someone who memorizes big teachings but never lives them is like a cowherd counting someone else's cows. Someone who knows a little but truly practices has done the real work.
