Devasena
Devasena (, ) is a Hindu goddess of aspiration, and the consort of the war god Kartikeya (Murugan). She is also known as Devayanai, Deivanai, and Deivayanai in Tamil texts. Her name is also spelled as Teyvanai or Tevayanai ().

Devasena is described as the daughter of the Prajapati Daksha in the Mahabharata, while some Sanskrit scriptures consider her as the daughter of Indra, the king of the devas (gods), and his wife Shachi. In the  Tamil iteration of the Skanda Purana, she is portrayed as the daughter of the god Vishnu, who is later adopted by Indra. She is betrothed to Kartikeya by Indra, when he becomes the commander-in-chief of the devas. In Tamil accounts, Devasena is generally depicted as an antithesis of Valli, her sister-wife; together they complete the deity. Devasena is generally depicted with Murugan, and is often also accompanied by Valli.

In Tamil Nadu, Devasena does not enjoy independent worship, but is venerated as Murugan's consort in most of his temples. She plays a greater role in the Tirupparankunram Murugan Temple, believed to be the site of her marriage. In East India, Devasena is worshipped in the form of Shashthi, where she is usually worshipped independently.

Etymology
The Sanskrit name of the goddess Devasena means "army of the gods" and thus, her husband is known as Devasenapati ("leader of Devasena"). The epithet Devasenapati is a pun, which also conveys his role as commander-in-chief of the devas.

She is called Deivanai or Deivayanai (Tamil, literally meaning "celestial elephant"), as she was raised by Indra's divine elephant, Airavata.

Legends and textual references
In North India, Kartikeya is generally considered as celibate and unmarried. Sanskrit scriptures generally regard only Devasena as the consort of Kartikeya, while in Tamil Nadu, he has two consorts, Devayanai (Devasena) and Valli. Devasena is described as a daughter of the king of the gods, Indra, and his wife Shachi or at least the adopted daughter of Indra.

Mahabharata 
The third book of Mahabharata narrates the tale of the birth of Kartikeya, which mentions Devasena. Devasena and Daityasena (literally "army of demons") are the daughters of Prajapati Daksha. Once, while the sisters are enjoying leisure at the banks of Lake Manasa, the asura (demon) Keshi abducts them so that he could marry them. While Devasena refuses, Daityasena consents. Meanwhile, the gods are defeated in a battle by the demons. Indra, who is searching for an ideal Devasenapati (commander of the army of the gods), reaches the place where Devasena is held captive. On her request, Indra defeats the demon and rescues her. Devasena asks Indra to find her a husband (pati) who can protect her and defeat the gods, the demons and the yakshas. Indra discusses the matter with the god Brahma and they agree that a son born of Agni would be suitable for being the Devasenapati, the husband of Devasena and the commander-in-chief of the gods. Accordingly, Agni is forced to have a son, who becomes Kartikeya. After many exploits which prove his supremacy over the gods, Kartikeya is made the general of the army of the gods and is married to Devasena by Indra. At this point in the text, Agni is identified with Shiva, who is proclaimed as the father of Kartikeya. Ultimately, with the aid of Devasena and Kartikeya, the gods defeat the demons. In this narrative, Devasena is identified with many other goddesses like Shashthi, Shri-Lakshmi, Kuhu-Sinivali, and others.

Kanda Puranam 
The Tamil manuscripts of the Sanskrit scripture Skanda Purana mentions Devasena and Valli as the incarnations of the daughters of Vishnu, Amritavalli and Sundaravalli, respectively. Thus, Murugan is regarded as the son-in-law of Vishnu, as their husband. An interpolation in the Tamil recensions of the scripture as well as the Kanda Puranam (the Tamil version of the Sanskrit Skanda Purana) narrate the story of the marriage of the two maidens to Murugan. The two maidens are fated to be married to the god. The elder sister Devasena is born as Amritavalli. She follows the path of traditional Hindu rituals and practices to gain her husband. Appeased by her penance, Indra adopts her as his daughter, and marries her to Murugan in an arranged marriage, following custom, after the latter triumphs over the asuras. The couple is described as taking their abode in the hills of Thiruttani, where one of Murugan's chief temples, Thiruthani Murugan Temple, stands. Another version describes the couple as residing in Svarga, the abode of the gods. Meanwhile, Valli is born as Sundaravalli. She is adopted by a tribal chieftain, and grows up as a huntress. Murugan wins Valli's hand and takes her to Thiruttani. The god is worshipped at the Thiruthani temple, flanked by Devasena on his left and Valli on his right. In the end, the trio settles in the abode of the gods and lives in harmony thereafter. An alternate ending found in Sri Lankan lore describes Murugan as staying on in the forest with Valli after their wedding at Kataragama, where his temple stands. Devayanai tries in vain to compel the god to return to the abode of the gods, but finally joins Kartikeya and Valli to reside in Kataragama.

Sangam 
Unlike the Skanda Purana which talks about harmony between Devasena and Valli, the Paripatal – part of Tamil Sangam literature – speaks about conflict, resulting in a battle between Devayanai's royal soldiers and Valli's hunter clan, which the latter win. Folk ecal (a folk poem, presented as a dialogue of two persons) tradition also talks about the mistrust and quarrel between the co-wives. In one version - where Devayanai is the elder sister of Valli, Valli tries to woo Murugan, before Devayanai's marriage. As per tradition, the elder sister has to be married off first. Infuriated, Devayanai curses Valli to be born in the forest in her next life, and the curse is then fulfilled when Valli is born as a huntress. In the Jayantipura Mahatmya, the details of which correspond to most of those found in the Skanda Purana tale, Devasena and Valli are married to Kartikeya from primal times. However, in this version, the god condemns Valli to be born on earth as punishment for mocking her sister Devayanai. The Thirumurugatrupadai from Sangam literature describes Murugan being accompanied by his chaste wife Devayanai and honoured by a procession of devas and rishis (sages).

Manava Purana 
According to the Mānava Purana, Brahma Savarni Manu's father, Upsaloka, is the son of Kartikeya and Devasena.

Iconography

Devayanai is generally depicted with her husband, particularly in an iconographic form called Senapati. She sits on the left thigh of the six-headed and twelve-armed Kartikeya. One of his arms holds her waist. Numerous depictions of the two exist at Tirupparankunram, the location of their marriage. However, in many south-Indian representations, when Murugan is depicted only with one consort, Valli is favoured over Devasena. In most Tamil depictions, Murugan is depicted with both his consorts standing besides him; Devasena is on his left-hand side. Her complexion is yellow; she is often depicted adorned with a crown, earrings, necklaces and ornaments. She wears a traditional sari and has two arms. She holds a lotus in her left arm, while her right hand hangs down.

Symbolism

The presence of the two consorts is said to denote the dual nature of Murugan, as the god of heaven and earth. Devasena, the celestial wife, is married in a traditional arranged marriage while the earthy Valli is won by Murugan, resulting in a love marriage. The consorts also represent a syncretism between the Shaiva and Vaishnava traditions, dedicated to Shiva and Vishnu, respectively. The son of Shiva, Kartikeya, becomes the son-in-law of Vishnu, due to the marriages. Both the consorts are identified with the soul (Atman), while their husband (pati, leader) represents God. The marriage of Devasena conveys Vaishnava ideals, where the soul (Devasena) remains detached from God; she has her own relative autonomy and earns the love of the god by her own merit. In contrast, the Shaiva philosophy says that God is attached to the soul (Valli), and hence he woos her. The Paripatal contains a Tamil panegyric dedicated to Murugan. It praises him as the god who is allowed to have two wives, Devasena – the daughter of Indra and Valli, a hunter princess. Murugan is described to equally spend his time on earth and in heaven. This is also conveyed by his wives, Devasena is a daughter of the heavens, while Valli is an earthly maiden.

Another interpretation regards the trio as the three eyes of Shiva. Valli and Devasena are representations of kriya shakti (the power of action) and Iccha-shakti (will-power) respectively; while their Kartikeya is the third eye, the symbol of the transcendental jnana-shakti (the power of knowledge). In Tamil literature, two kinds of love are mentioned: karpu ("chastity"), love bound in the traditional marriage, represented by Devasena and kalavu, love before marriage, conveyed by Valli. Devasena represents "the conventional, control, ritualized approach to worship" God, while Valli is worship through "ecstasy and self-abandonment". Devasena is the epitome of chastity and purity. In trinity of gunas, she is the middle guna – rajas, symbolizing "rulership, fixity, and stability". Kartikeya is the most superior Sattva (pure), while Valli is the inferior tamas (dark). As per another interpretation, Devasena is an embodiment of how virtuous people should live considering her steadfast and uncompromising fight against evil.

Worship
Tirupparankunram Murugan Temple in Tirupparankunram near Madurai is dedicated to Murugan and Devayanai. It is believed that she was married to the god at this location. A festival icon depicts the god seated close to his divine consort. The Latankovil temple at Yanaimalai is one of the earliest temples dedicated to the divine couple.

Devasena and Valli, the consorts of Murugan, do not have independent temples dedicated to them. Their images are installed in shrines of Murugan, where they flank their consort on either side. They are worshipped with Murugan and receive offerings as part of his worship (see Puja (Hinduism)). A fast is observed on Tuesdays to placate the consort goddesses. Festival icons of Murugan used during temple festival processions generally depict him with his consorts.
