All the great Teachers have laid stress upon the importance, not of envisaging an enormous period of time before you to do the difficult things of the spiritual life, but to pay attention to the little passing moments, the minutes and hours of each day. Therefore they taught: Fill the day full; watch over it, guide it; regard each single day as if it were the last day that you knew you were going to live. It has a wonderful effect upon the inner spiritual life, if we live each single moment with that awareness, that watchfulness, which has the feeling in it that after all we would not wish to leave an inharmonious impression upon those with whom we are associated, if at the close of the day we were leaving them not to return. It is an idea that is worth remembering and bringing to bear in every single moment and every single hour of the day.
