मनोपुब्बङ्गमा धम्मा, मनोसेट्ठा मनोमया। मनसा चे पदुट्ठेन, भासति वा करोति वा। ततो नं दुक्खमन्वेति, चक्कंव वहतो पदं॥
All mental phenomena have mind as their forerunner; they have mind as their chief; they are mind-made. If one speaks or acts with an evil mind, 'dukkha' follows him just as the wheel follows the hoofprint of the ox that draws the cart - Buddha
Dukkha - Pain
