Dhammapada Verse 145
The Story of Samanera Sukha
Sukha was made a samanera at the age of seven years by Thera Sariputta. On the eighth day after being made a samanera he followed Thera Sariputta on his alms-round. While doing the round they came across some farmers irrigating their fields, some fletchers straightening their arrows and some carpenters making things like cart-wheels, etc. Seeing these, he asked Thera Sariputta whether these inanimate things could be guided to where one wished or be made into things one wished to make, and the thera answered him in the affirmative. The young samanera then pondered that if that were so, there could be no reason why a person could not tame his mind and practise Tranquillity and Insight Meditation.
