Mahishasura

Mahishasura (Sanskrit: महिषासुर, IAST: Mahiṣāsura) is a bovine asura in Hinduism. He is depicted in Hindu literature as a deceitful demon who pursued his evil ways by shape-shifting. Mahishasura was the son of the asura Rambha and the brother of buffalo-demoness named Mahishi. He was ultimately killed by the goddess Durga with her trishula (trident) after which she gained the epithet Mahishasuramardini ("Slayer of Mahishasura"). Mahishasura had a son named Gajasura.
The Navaratri ("Nine Nights") festival eulogises this battle between Mahishasura and Durga, culminating in Vijayadashami, a celebration of his ultimate defeat. This story of the "triumph of good over evil" carries profound symbolism in Hinduism, particularly Shaktism, and is both narrated as well as reenacted from the Devi Mahatmya at many South and Southeast Asian Hindu temples.
The Mahishasura Mardini Stotra by Adi Shankara was written to commemorate her legend.
Mahishasura is a Sanskrit word composed of Mahisha meaning "buffalo" and asura meaning "demon", translating to "buffalo demon". As an asura, Mahishasura waged war against the devas, as the devas and asuras were perpetually in conflict. Mahishasura had gained the boon that no man could kill him. In the battles between the devas and the demons (asuras), the devas, led by Indra, were defeated by Mahishasura. Subjected to defeat, the devas assembled in the mountains where their combined divine energies coalesced into the goddess Durga. The newborn Durga led a battle against Mahishasura, riding a lion, and killed him. Thereafter, she was named Mahishasuramardini, meaning The Killer of Mahishasura. According to the Lakshmi Tantra, it is the goddess Lakshmi who slays Mahishasura instantaneously, and extolling her feat is described to offer everlasting supremacy.
Mahishasura's legend is told in the major texts of the Shaktism traditions known as the Devi Mahatmya, which is part of Markandeya Purana. The story of Mahishasura is told in the chapter where Markandeya is narrating the story of the birth of Savarnika Manu. Per the Markandeya Purana, the story of Mahishasura was narrated in the second Manvantara (approximately 1.3 billion years ago, as per the Vishnu Purana) by Maharishi Medha to a king named Suratha. Mahishasura is described as an evil being who can change his outer form, but never his demonic goals. According to Christopher Fuller, Mahishasura represents the forces of ignorance and chaos hidden by outer appearances. The symbolism is carried in Hindu art found in South Asia and South-East Asia (e.g., Javanese art), where Durga is shown as a serene, calm, collected and graceful symbol of good as she pierces the heart and kills the scared, overwhelmed and outwitted Mahishasura.
Durga slaying Mahishasura is a prominent theme which was sculpted in various caves and temples across India. Some of the prominent representations are seen at the Mahishasuramardini caves in Mahabalipuram, the Ellora Caves, in the entrance of Rani ki vav, Hoysaleswara Temple in Halebidu and many more temples across India. The worship of Durga during Durga Puja in Bihar, West Bengal, Jharkhand, Odisha and other eastern states is represented in Pandal which depict Durga killing Mahishasura. The legend of Mahishasura has also been inspiration for films, plays and dance dramas.
The popular legend is that Mysore (Mahishooru) gets its name from Mahishasuramardini, a manifestation of goddess Durga. The buffalo demon Mahishasura, states the regional tradition, had terrified the local population. It is believed that goddess Durga (Chamundeshwari) killed Mahishasura on top of the Chamundi Hills. The spot was constructed as the Chamundeshwari Temple in Mysuru, an event that is annually celebrated at Navaratri and Mysuru Dasara. The British Era in India saw the name change to "Mysore" and later Kannadized back into "Mysuru".
The temple of the city's guardian deity, Chamundeshvari, has a giant statue of Mahishasura on the hill facing the city. The earliest mention of Mysore in recorded history may be traced to 245 B.C., i.e., to the period of Ashoka when on the conclusion of the third Buddhist convocation, a team was dispatched to Mahisha Mandala.
