It says in the sutra, and Nichiren repeats it in his letters, it only takes one candle to instantly eliminate the darkness that has filled a cave for thousands of years. Chanting Odaimoku is like that candle. No matter how small or feeble, that one candle does begin to light up your life. That spark of hope can be the foundation of faith in your life that anything is possible to change if you follow the teachings of the Lotus Sutra.
