[E]ach of the twenty-eight chapters of the Lotus Sūtra is as meritorious as the others, but above all chapter 2, “Expedients,” and chapter 16, “Duration of the Life of the Buddha,” are the most worthy chapters. The other 26 chapters are like branches and leaves of these two. Therefore, you should chant all of chapters 2 and 16 for daily services. You may also practice writing these two chapters.

The merits of these two chapters are accompanied by those of the other 26 chapters just as a body is followed by its shadow and a gem has its intrinsic value. Therefore, when you chant these two chapters, even if you don’t chant the other 26 chapters, the merit of chanting them all is yours.
