If one believes in this Object of Worship and chants Daimoku there is no prayer that will go unanswered, no sin that will go uneradicated, no fortune that will fail to come and no truth that will fail to become evident. Even a tarnished mirror will shine like a jewel if it is polished.
In "On Attaining Buddhahood" the Daishonin also teaches us the importance of chanting Daimoku every day by saying
Even a tarnished mirror will shine like a jewel if it is polished. A mind which at present is clouded by illusions originating from the innate darkness of life is like a tarnished mirror, but once it is polished it will become clear, reflecting the enlightenment of immutable truth. Arouse deep faith and polish your mirror night and day. How should you polish it? Only by chanting Nam-Myoho-Renge-Kyo.
Difficulties and adversities enable us to eradicate all the slanders of the Law that we have committed in the past. By believing in the power of the Mystic Law we can realise the principle of changing poison into medicine. Great difficulties are challenges which foster faith and create commitment to this profound practice.
On the Buddha's Behaviour The Daishonin says;
With deep commitment, anything is possible with this practice and all obstacles in terms of illness, unhappiness, adversity, and material and emotional difficulties can be overcome as remarkable changes occur in a person`s life enhancing and empowering that person with the Law.
