Interest may be called life; indifference, death; interest, light; indifference, darkness. And yet through the darkness there is a goal to be reached, as there is something to be attained through the light. A person who is one day interested and the next day indifferent has not depth either to his interest or to his indifference. Neither can he attain something by his interest, nor can he reach something by his indifference. It is the power motive which stands as the greatest power, as a secret behind this creation; and it is the absence of that power which very often gives indifference, stands as a mystery behind that life which is assimilating.
