At first one may seem to have faith in the Lotus Sutra, but it is hard to maintain that faith to the last. Water for example may be stirred by the wind, or blossoms may lose their hue with the fading of the morning dew. How then have you been able to persist in your faith up until today? It must be thanks entirely to the blessings you have acquired in previous existences, and to the care bestowed on you by Shakyamuni Buddha. How heartening is that thought, how heartening indeed!
