"Any object of desire is bound to bring frustration. Any expectation is bound to turn into frustration. Expectation is the beginning of frustration, the very seed. Beware of it!"

Next Quote

It is within your hands to be frustrated in life or not. Just your expectations should become smaller, smaller, smaller, and in the same proportion the frustration will become smaller. A day will come when there will be no expectation; then you will never come across any frustration.
