A desire arises in the mind. It is satisfied immediately another comes. In the interval which separates two desires a perfect calm reigns in the mind. It is at this moment freed from all thought, love or hate. Complete peace equally reigns between two mental waves.
Understand clearly that when a great need appears a great use appears also; when there is small need there is small use; it is obvious, then, that full use is made of all things at all times according to the necessity thereof.
