As it is with death so is passage of Time, Just before one passes on, their life experiences replays itself in there faces, it behaves as if in askance if you go back if u couldve done things differently. We have grown in these journey with Yi Yun wence he was just a novice nobody till he has become an entity nobody can even try to contend with. A life of cultivation, dead and ressulection, leaving and coming back... It all seems like a dream or is it not... Ones dream is another's realities..
