A Buddhist Monk

A buddhist monk was visiting places along with his disciples. In this mission, he came to a village where in, there was a famous entrepreneur. The Monk was preaching the villagers to lead a simple life. Influenced by it, people started living with the basic needs, abandoning all the luxuries.
But, this in turn, was affecting the entrepreneur. Tracing out the reason for decrease in the output of business, entrepenuer approaches the monk with rage of anger and abuses him with all words. The monk unperturbed, inspite of all this, remains placid. After a while the entrepreneur asks monk "why do you keep still."
Then the monk questions "If you offer me an apple and i don't receive it, whose apple would it be?"
