It is not only for the Japanese or the people of one particular country or ethnic group. That's because when we chant daimoku, our lives become one with the life of the Buddha, enabling us to draw forth the inexhaustible strength to carry out our human revolution and to help others do the same. Fame, wealth and social status alone do not guarantee happiness. Many wealthy individuals suffer terribly within their mansions. Some people may be so bound up in vanity that they can find no peace of mind.
Many famous people feel miserable the moment they slip from the limelight.
It is not at all uncommon to find such disparities among people whose lives are otherwise quite similar. The disparities arise due to differences in people's inner states, differences in their hearts. Nor can it be said that the advance of science or economics necessarily brings happiness. In every case, whether we feel happy or unhappy ultimately depends on us. Without changing our state of life, we can find no true happiness.
