We accumulate great good fortune through our earnest prayers, devotion and efforts for the sake of Buddhism, kosen-rufu and humankind. Prayer without action is not the way of Nichiren Buddhism.
There may be times when others seem enviable. But others are others and you are you. Rather than comparing your joys and sorrows to those of others, you should aim to surpass your limits in the situation you are in right now. Those who can do this are the true victors in life.
