“Whether or not your prayer is answered will depend on your faith; [if it is not] I will in no way be to blame.
When water is clear, the moon is reflected. When the wind blows, the trees shake. Our minds are like the water. Faith that is weak is like muddy water, while faith that is brave is like clear water. Understand that the trees are like principles, and the wind that shakes them is like the recitation of the sutra.”
This letter was written at Minobu in 1280 in response to a petition from the lay nun Nichigon who is believed to have been either a relative of the lay priest Takahashi, a central figure among the believers in Fuji District of Suruga Province, or the mother of Nichigen, a priest of Jissō-ji temple in the same province who converted to Nichiren Daishonin’s teachings.
In this short letter to the lay nun, the Daishonin emphasises on the importance of deepening of one’s faith. Fulfillment of prayers is based on the faith one has on the Lotus Sutra and while chanting Nam Myoho Renge Kyo. A weakening faith in the Sutra is like murky water that is filled with doubt (mud). As we strengthen our faith, we cleanse this water which ultimately becomes crystal clear- a faith that is brave and unshakable devoid of doubt.
