Practicing is regarded as the principal conduct in the teaching of the Lotus Sutra. Although we might meet a wonderful teaching, we do not always practice the teaching in our lives. The teaching then becomes meaningless. For example, if you wish to become a good tennis player and you memorize all the rules and theories perfectly, this does not mean you will be able to play tennis. Why? Because you have not practiced on the court. Therefore, learning diligently first, and then practicing the teaching after having learnt the theory, are the conditions which give rise to enlightenment. This is called “learning and practicing of the dual path.”
