>Never let life ’s hardships disturb you. After all, no one can avoid problems, not even saints or sages.
Just chant Nam-myoho-renge-kyo, and when you drink sake, stay at home with your wife. 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. Then you will experience boundless joy from the Law. Strengthen your faith more than ever.
With my deep respect,
The twenty-seventh day of the sixth month in the second year of Kenji (1276) (The Major Writings of Nichiren Daishonin, vol. 1, pp. 161-62)
