Kartikeya, son of Lord Shiva, and Goddess Parvati is also known as Subramaniam, Skanda, Guha, Shadannana or Sanmukha (because he has six faces). He represents a person of perfection. He is the war God, the Hindu equivalent of Mars and Ares. He was created by all the Gods to lead the heavenly hosts and destroy the demons. He is the most masculine and fierce of all the Gods. He is also fire, Agni and is very Pitta (fiery) in nature.
According to the Hindu Mythology Shiva-the destroyer god, was destined to have a son who will be a great warrior.
Shiva and his wife, Parvati, created a being with five faces. A glowing spark emerged from each face. Shiva sent the five-faced being into the- GANGA THE HOLY RIVER. The five sparks floated and each converted into a child. Young women found them in the forest pond, and they started nursing one of the children.
When Shiva and Parvati eventually took their children back, Parvati did not know how she could take care and feed all five. Shiva solved her problem by merging the children into one being with six heads - one for each of the children, representing the five senses, and a final head to combine the senses into one, symbolic of the mind and power of Shiva. The six-headed child was the much-awaited WARRIOR GOD THE KARTIKEYA.
