After we live this world, what is happiness, what is unhappiness, what kind of answer is found, then pass the ticket of happiness to those who are born next. . . In that way, I think people have been born and connected with life.
The small variety of emotions we experience everyday may have been experienced by ancestors who lived 100 years ago.
We live in this world confront the problems that people living in the past world could not solve and fighting and entrusting tasks and hopes to those who live the next future while fighting.
People wish to be free, but it is the life entrusted with the desires of many of the ancestors who lived in the past. It carries a very big mission.
