A person who has truly seen the world is one who, after understanding the complexity of the world and the realities of human nature, still remains calm and gentle: able to accept differences, not quick to judge, not overestimating relationships nor losing their bottom line; calm and composed when facing issues, modest and humble, enjoying solitude as well as avoiding unnecessary disturbances; not obsessed with gains and losses, going with the flow; even after understanding worldly tricks, still choosing kindness and purity; ultimately making peace with regrets, accepting imperfection, and living peacefully with life.
