A Phrase from the Gosho “Happiness in This World”
There is no true happiness other than upholding faith in the Lotus Sutra. This is what is meant by “peace and security in their present existence and good circumstances in future existences.” Though worldly troubles may arise, never let them disturb you. No one can avoid problems, not even sages or worthies.
Drink sake only at home with your wife, and chant Nam-myoho-renge-kyo. Suffer what there is to suffer, enjoy what there is to enjoy. Regard both suffering and joy as facts of life, and continue chanting Nam-myoho-renge-kyo. no matter what happens. How could this be anything other than the boundless joy of the Law?

A Phase from the Gosho:
Both of you have continued believing in the Lotus Sutra; thus you are now ridding yourselves of your grave offenses from the past. For example, the flaws in iron come to the surface when it is forged. Put into flames, a rock simply turns to ashes, but gold becomes pure gold. This trial, more than anything else, will prove your faith genuine, and the ten demon daughters of the Lotus Sutra will surely protect you.
