How does a jnani deal with predestined karma

The potter’s wheel goes on turning even after the potter has ceased to turn it because the pot is finished. In the same way, an electric fan goes on revolving for some minutes after we switch off the current. The prarabdha – predestined karma – which created the body will make it go through whatever activities it was meant for. But the jnani – the knower – goes through all these activities without the notion that he is the doer of them. It is hard to understand how this is possible. The illustration generally given is that the dnyani (self relaised soul ) performs action in some such way as a child that is roused from sleep to eat eats but does not remember next morning that it ate. “- Ramana Maharshi
