https://en.wikipedia.org/wiki/Skanda_(Buddhism)
Origins[edit]
Stories vary on how Skanda was accepted into the traditional Chinese Buddhist pantheon. Some have proposed that Skanda's features were adapted from a Chinese deity who appeared in the Chinese classical
Ming novel
Canonization of the Gods. However, the existence of illustrated Skanda images predating the Ming Dynasty set his origins back to an earlier period in the development of Chinese Buddhism.
Skanda is described as a young man fully clad in the armor and headgear of a Chinese general, and is usually leaning on a
vajra staff. Some suggest that Skanda may have come from
Hinduism as the war deity
Kartikeya / Muruga (Tamil), who bears the title Skanda. Others point out that Skanda might also be a manifestation of
Vajrapani, a bodhisattva who bears some relations to Skanda because they both wield
vajras as weapons, are portrayed with flaming halos, and are both heavenly protectors of Buddhism. Skanda may be connected through Vajrapani through a theory to his connection to
Greco-Buddhism, as Wei Tuo's image is reminiscent of the
Heracles depiction of Vajrapani.
Although Skanda is only a
deva, he is very often addressed as a bodhisattva.
As Miao Shan's lover[edit]
When the bodhisattva Avalokitesvara was reincarnated as the princess Miao Shan, Skanda (known as Wei Tuo in this story) was one of her cruel father's generals. He loved Miao Shan but realized he could not possibly be a proper partner to her, since she was a pure person. However, Wei Tuo was inspired by Miao Shan's kindness so he decided to stay faithful and devoted to Miao Shan, even if she wasn't his wife. The two escaped Miao Shan's father, and the general-suitor helped build Miao Shan a temple and a kingdom of her own. Soon however, the cruel king found them and killed them both. The general, because of his devotion to Guan Yin, transformed into a bodhisattva himself, who vowed to always serve and protect Guan Yin. His appearance as a Chinese general is the direct forbear to his connection with Miao Shan.
As a warrior[edit]
Another story says that Miao Shan was told to be killed by her grandmother. Her grandmother forced Miao Shan to commit suicide by leaping into the sea because she was thought to have been an incarnation of a demon, when in fact she was not. The emperor told a loyal soldier named Luo Ping to pretend to throw Miao Shan to the ocean. He brought her with Yin Ma, the mother of Wei Tuo to her village. Years passed, an evil fish demon came. A disloyal soldier named Huo Yi, was sent from the fish demon to kill Miao Shan. The fish demon wanted revenge on Miao Shan because she was the incarnation of
Ci Hang Da Shi, a Buddhist deva that put her in a lotus pond. Huo Yi and his troops went to the village where Miao Shan and Wei Tuo lived and fought. Huo Yi's son killed Wei Tuo. After Miao Shan became the bodhisattva Avalokitesvara, she made Skanda a bodhisattva guardian. He became a bodhisattva because he took care of Miao Shan and loved her as a sister.
According to the lunar calendar, his birthday is at the 3rd day of the 6th lunar month.
