Shanmukha / Arumukam · षण्मुख
The six-faced, twelve-armed form uniting the six infants; the faces govern the senses-and-mind and radiate in the six directions.
God of war and victory, commander-in-chief of the deva armies, and patron of wisdom, valour, and tapas.
Who Kartikeya (Murugan) is
Kartikeya is the second son of Shiva and Parvati, younger brother of Ganesha, born expressly to lead the celestial hosts and destroy the asura Tarakasura. In the Tamil tradition he is Murugan, the supreme deity of beauty (azhagu) and youth, worshipped as Subramanya and Skanda. He is the eternal kumara (ever-youthful celibate in the northern tradition) and Senapati of the devas.
What Kartikeya (Murugan) embodies
He embodies the principle of jnana-shakti, the spear (Vel) of discriminating wisdom that pierces ignorance and ego. As Shanmukha, his six faces signify mastery over the five senses plus the mind, and the radiance of the six Krittikas. He is the warrior-tattva in whom divine power (Shakti) is wielded with perfect knowledge, making valour itself a form of grace.
Birth & origin
The core Puranic account: when the asura Tarakasura grew invincible through a boon that only a son of Shiva could kill him, the devas roused Shiva from tapas. The seed (tejas) of Shiva, too potent to be borne, passed through Agni and was deposited in the Ganga, which bore it to a thicket of reeds (sara-vana); there it became a six-faced child suckled by the six Krittika star-goddesses, hence Kartikeya / Shanmukha / Saravanabhava. Parvati united the six infants into one six-faced form. Major variants differ on the carriers and womb: the Mahabharata (Vana/Shalya Parvans) has Agni and Svaha central, with the Krittikas as nurses; the Shiva and Skanda Puranas emphasize Shiva's tejas through Agni and Ganga; the Tamil tradition (Kanda Puranam of Kachiappa Sivachariyar) describes six sparks from Shiva's third eye carried to the Saravana Poigai. He is thus called Gangeya, Agnibhu, and Kumara.
When: Anadi (eternal/beginningless) as an aspect of Shiva; his principal manifestation is placed in earlier yugas, with the Tarakasura episode and the Devasena marriage as the defining cosmic event.

Key stories
The Slaying of Tarakasura
Tarakasura, empowered to be slain only by a six-day-old son of Shiva, terrorized the three worlds. Newly born and made general of the gods at Indra's request, Kartikeya led the deva army and pierced the asura with his Vel, restoring the cosmic order. This victory is the reason for his birth and the basis of his title Mahasena.
Surapadma and the Cleaving of the Mango Hill (Soorasamharam)
In the Tamil Kanda Puranam, Murugan wages war on the asura Surapadma at Tiruchendur. When Surapadma takes refuge as a great mango tree in the sea, Murugan splits him with the Vel; the halves become his peacock vahana and the rooster of his banner. The episode is re-enacted yearly as Soorasamharam during Skanda Sashti.
The Fruit of Wisdom and Valli's Wooing
Narada brought a divine fruit; Shiva set it as a prize for whoever first circled the world. Ganesha simply circumambulated his parents as the whole cosmos and won, while Kartikeya, who had raced around the earth, withdrew in pique to Palani as a renunciate (Dandayudhapani). In the south he later wins Valli, the hunter-girl, with Ganesha's aid, uniting bhakti's grace with divine play.

How Kartikeya (Murugan) is worshipped
Worshipped with abhishekam (notably the famed panchamrita and sandal-paste abhisheka at Palani), archana of the Vel, kavadi-bearing and the carrying of milk-pots (paal-kudam) as vows, and recitation of the Skanda Sashti Kavacham, Subramanya Bhujangam, and Kandar Anubhuti. Favourite offerings include the Palani panchamritam (banana, jaggery, dates, ghee, candy/sugar), tender coconut, milk, honey, and flowers; vibhuti and the planting of the Vel are central. Tuesdays and the Sashti tithi (sixth lunar day) are especially sacred to him.
The teaching
Kartikeya teaches that true valour is wisdom in action: the Vel is jnana-shakti, the sharp discernment that destroys the asura of the ego (ahankara) and ignorance, not merely an outer enemy. As Guha, the indweller of the heart-cave, he turns the warrior's energy inward, and as the ever-youthful Kumara he embodies the freshness and one-pointedness of the awakened seeker. Devotion to him (as in Arunagirinathar's Tiruppugazh) unites fearless surrender with the pursuit of self-knowledge.
