Thaipusam
Thaipusam or Thaipoosam () is a Tamil Hindu festival celebrated on the full moon of the Tamil month of Thai (January/February), usually coinciding with Pushya star, known as Pusam in Tamil. The festival commemorates the legend of the goddess Parvati offering her son, Murugan (Kartikeya) a vel (a divine spear) so he could vanquish the asura Surapadman and his brothers. It is also commonly believed that Thaipusam marks Murugan's birthday; though some other sources suggest that the date of Vaikasi Visakam, which falls on the Vaikasi month (May/June), is Murugan's birthday. Thaipusam is mainly observed in countries where there is a significant presence of Tamil community such as India, Malaysia, Mauritius, as well as other places where ethnic Tamils reside as a part of the local Indian diaspora population such as Canada, Singapore, South Africa, Fiji, the United States, Réunion, Indonesia, Thailand, Myanmar, Trinidad and Tobago, Guyana, Suriname, Jamaica and the other parts of the Caribbean. It is a national holiday in many countries such as Malaysia and Mauritius. In India its a state holiday in Tamil Nadu. In certain states of Malaysia and in the nations of Mauritius, it is also a government and a bank holiday. Etymology 
The name Thaipusam is a portmanteau of the name of the Tamil month of Thai, and the name of the star, Pusam, the Tamil rendering of the Sanskrit Pushya. This particular star is at its highest point during the festival. The name of the star is rendered Pooyam in Malayalam. Legend

According to the Kanda Puranam, the Tamil iteration of the Skanda Purana, three asuras (a race of celestial beings) named Surapadman, Tarakasuran, Singamukhan performed austerities to propitiate Shiva. The deity granted them various boons, including the ability to conquer the three worlds, as well as immortality. The three brothers subsequently oppressed the celestial deities known as the devas and started a reign of injustice and tyranny in their respective realms. When the deities pleaded Shiva for his assistance, he manifested five additional heads, and a divine spark emerged from each of them. Each spark developed into a baby boy, raised by the maidens known as the krrtikas (personifications of the Pleiades). When they were embraced by Parvati, the six boys fused into one, and the six-headed Murugan was born. Parvati granted him a divine spear, known as the vel. Accompanied by Virabahu, his commander-in-chief, the former's eight brothers, as well as the forces of the devas, the deity waged war on the asura brothers. In the final phase of the conflict, Murugan battled Surapadman, who employed his magical arts to fight the deity. Murugan split the asura in two with his divine spear. Having been granted immortality, the two halves of the asura transformed into a mango tree and retreated to the ocean, intending to overwhelm the earth. When the deity bisected the tree, the asura turned into a peacock and a rooster. Murugan decided to adopt the peacock as his mount, and take on the rooster as his flag. Murugan is a deity associated with yogic discipline and austerities, and is regarded by his adherents to be capable of offering mukti (spiritual liberation) to all those who venerate him. Kavadi Attam
The Kavadi Attam ("kavadi dance") is a ceremonial act of devotional sacrifice through dance, food offerings, and bodily self-mortification. It is often performed by devotees during the festival of Thaipusam in honor of Murugan. The kavadi is a semicircular, decorated canopy supported by a wooden rod that the pilgrim carries on their shoulders to the temple. The devotee makes the pilgrimage (the nadai payanam) with bare feet, bearing food offerings on the kavadi. Depending on the location of the temple, this walk to the temple can take more than a week. The temple of Murugan in Palani is a popular destination, as it is one among the arupadai veedu ("six houses" - the sites sacred to Murugan). The Palani Murugan temple also has a reputation as a place of healing. Bogar (an ancient siddhar and devotee of Murugan) made the statue of Murugan in Palani, with the mixture of several sidhha medicines. Devotees prepare for the celebration by keeping their body always clean, doing regular prayers, following a vegetarian diet and fasting before the Thaipusam. Kavadi-bearers have to perform elaborate ceremonies at the time of assuming the kavadi and at the time of offering it to Murugan. The kavadi-bearer observes celibacy and consumes only certain types of foods known as satvik food, once a day, while continuously thinking of God. On the day of the festival, devotees shave their heads and undertake a pilgrimage along a set route, while engaging in various acts of devotion, notably carrying the various types of kavadi. The devotees believe that worshiping lord Murugan every year in this way makes them physically and mentally healthy, and helps clear them of karmic debts they may have incurred. At its simplest, the pilgrimage may entail walking the route carrying a pot of milk, but mortification of the flesh by piercing the skin, tongue or cheeks with vel skewers is also common. In addition, some pierce their tongues or cheeks, all the way through, with a small spear. A similar practice is performed by the Nagarathar community in Pazhani, India. This is known as the Nagarathar Kavadi. Thaipusam in India
