You are right when you say that setting a good example for the boys is the best precept. There is a saying that an example is better than a precept. Our exemplary character depends on strictly following the four principles, and this will conquer the whole world. Our boys and girls in London, by their exemplary character have drawn the attention of many respectable persons and even some public papers.
Letter to Aniruddha, 4 February 1969
