The Annotations on the Words and Phrases of the Lotus Sūtra says: “If the practice of the spiritual contemplation is consistent with the teaching of the Lotus Sūtra, it will become a wonderful way of practice different from such vain efforts as counting the treasures of other people. This shows that the Great Concentration and Insight is merely a means to attain the objective for knowing the Lotus meditation (like a coop which is unnecessary when the fish is caught). If a person understands this meaning, he can really obtain the essence of the Lotus Sūtra.
