Dear swezwakov,
I'm also a bit confused about Tripitaka being one of the characters of the Hsi Yu Chi. If you are referring to the companions of
Sun Wukong (孫悟空), these are called the pig-monster
Zhu Wuneng (豬悟能), and the river monster
Sha Wujing (沙悟淨). The latter is associated with a robe in the story.
Sha Wujing (沙悟凈
WG: Sha Wu-ching) is one of the three helpers of
Xuanzang in the classic Chinese novel
Journey to the West. In the novels, his background is the least developed of the pilgrims.
Like
Zhu Bajie, Wujing was originally a
general in
Heaven. Once, he became very furious and destroyed a valuable
vase. Other sources mention that he did this unintentionally. Nevertheless, he was punished by the
Jade Emperor, who had him stroked 800 times with a rod and exiled to earth, where he was to be
reincarnated as a terrible man-eating Sand
Demon. There he lived in a
river with
sandy waters. Every seven days a sword would be sent from heaven to stab him 100 times in the chest before flying off.
Sha Wujing's appearance was rather grisly; he had a red
beard and his
head was partially bald; a necklace consisting of skulls made him even more terrible. Still, he used the weapon he had in heaven, namely a staff with blades (one crescent-shaped, the other like that of a shovel) on either end. There is an interesting story about the necklace of skulls. An earlier group of nine monks on a pilgrimage West to fetch the scriptures met their end at the hands of Wujing. Despite their pleas for mercy, he devoured them, sucked the marrow from their bones, and threw their skulls into the river. However, unlike his other victims who found their way to the river bottom, the skulls of the monks floated. This fascinated and delighted Wujing, who strung them on a rope and played with them whenever he was bored.
Later,
Guanyin, the
bodhisattva of compassion, and her disciple Prince
Moksa came searching for powerful bodyguards in preparation of
Sanzang's journey west. She recruited Wujing in exchange for some relief from his suffering. She then converted him and gave him his current name, Sha Wujing. His surname "Sha" means "Sand", while his
Buddhist name Wujing means "Awakened to Purity" or "Aware of Purity". Finally, he was instructed to wait for a monk who would call for him. When Wujing does meet Sanzang, the demon is mistaken for an enemy and attacked by
Sun Wukong and
Zhu Bajie. Guanyin was forced to intervene for the sake of the journey.
After everything was cleared up, Sha Wujing became the third
disciple of Sanzang. Now, he was clad in a
Buddhist pilgrim's robe and his skull-necklace was turned into a
monk's one. His appearance also changed; from now on he looked more like a
human, yet still ugly. During the Journey to the West, his swimming ability was quite useful. Sha Wujing was actually a kind-hearted and obedient person and was very loyal to his master, among the three he was likely the most polite and the most logical. At the journey's end, Lord Buddha transformed him into an
arhat or luohan.
As the third disciple, even though his fighting skills are not as great as that of Wukong or Bajie, he is still a great warrior protecting
Sanzang and can incorporate a little brain to beat the enemy rather than by pure brute strength. He knows 18 transformations.
In
Japan he was seen as a
kappa, another fearsome kind of water demon.
hope this helps,
Bob
