Evolution goes on step by step, not hurrying. Indifference is attained by developing interest, and by developing discrimination in one's interest. Instead of going backward one should go forward in one's interest; then one will find that a spring will rise naturally in one's heart, when the heart has touched the zenith in the path of interest. Then the fountain of interest will break up gradually, and when this happens, one should follow this trend, so that in the end one may know what interest means, and what indifference means.
