A puzzled man asked the Buddha: I have heard that some monks meditate with expectations, others meditate with no expectations, and yet others are indifferent to the result. What is the best?

The Buddha answered: Whether they meditate with or without expectations, if they have the wrong ideas and the wrong methods, they will not get any fruit from their meditation.

Think about it. Suppose a man wants to have some oil and he puts sand into a bowl and then sprinkles it with salt. However much he presses it, he will not get oil, for that is not the method.
