What Is the True State of Diligence?

Those who apply effort can ponder problems even in the middle of the night, while those who do not apply effort do not ponder problems even during the day. This shows that true diligence is the diligence of the manas; He does not care whether it is day or night. The diligence of the mind consciousness is intermittent, so at night it is unable to ponder problems. Even if during the day the manas only attends to trivial matters, the mind consciousness still cannot be diligent, for He cannot escape the baton of the manas.
