It is easier to begin putting faith in the teaching of the Lotus Sūtra than to keep on believing in it to the very end. It is as though water flows in the direction of the wind and the color of flowers fade with dew.
You have steadfastly maintained your true faith in the Lotus Sūtra till today, which is very rare. How do you think you have had such a strong true faith in the Lotus Sutra? It was solely due to the good karma you accumulated during your lives in the past, in addition to the divine protection of the Buddha.
