A wise man and his disciple were walking across a deserted village, where they met a poor family. The house was in a dilapidated state. Though they had not much hope of getting anything there, since they were hungry and thirsty, they stopped for a few hours.
To their surprise they were well received. The wise man enquired, “This is a very poor place, far away from anything. How do you survive?” The head of the family said, “You see that cow? That’s what keeps us going.”
The wife interrupted and said “The cow gives us milk, some of it we drink and some we make into cheese. When there is extra, we go into the city and exchange the milk and cheese for other types of food. That’s how we survive.”
The wise man thanked them for their hospitality and left. In the night, the wise man ordered the disciple to go back and push the cow off the cliff.
