Yammakavagga “The Pairs” (verses 1-20)
Mind precedes all mental states. Mind is their chief; they are all mind-wrought. If with an impure mind a person speaks or acts suffering follows him like the wheel that follows the foot of the ox. (Verse 1)
Translator: Acharya Buddharakkhita
Alternate translation: Phenomena are preceded by the heart, ruled by the heart, made of the heart. If you speak or act with a corrupted heart, then suffering follows you — as the wheel of the cart, the track of the ox that pulls it.
Translator: Thanissaro Bhikkhu
Alternative translation: All that we are is the result of what we have thought: it is founded on our thoughts, it is made up of our thoughts. If a man speaks or acts with an evil thought, pain follows him, as the wheel follows the foot of the ox that draws the carriage… If a man speaks or acts with a pure thought, happiness follows him, like a shadow that never leaves him.
