The Greeks called it kleos aphthiton: fame that never wilts. Achilles at Troy was offered two fates: sail home and live long and be forgotten, or die young and become a story sung forever. He chose the story. The body dies, but the tale walks on its own.
Sun Wukong (孫悟空) guided a monk west to bring the sutras to China and fought every demon on the road. When it ended, the Buddha gave him the name Victorious in Strife. Not for the battles he won, but for the enemy he finally beat: the anger and hunger in his own mind. He awakened and became enlightened.
Centuries on, the story chose a new body. Akira Toriyama called him Son Goku, 孫悟空, the same name. The tail and the staff and the cloud went with him. Here, Goku is a tale of a simple lesson: train the body, train the mind, love while you do it. When Goku reaches Ultra Instinct, he stops thinking and lets go. That is the place the monkey also reached.
The name says it in two characters. 悟 is to awaken. 空 is the void. Awake to emptiness.
