Thai Poosam
The festival includes ritualistic practices of Kavadi Aattam, a ceremonial act of sacrifice carrying a physical burden as a means of balancing a spiritual debt. Worshipers often carry a pot of cow milk as an offering and also do mortification of the flesh by piercing the skin, tongue or cheeks with vel skewers. Devotees prepare for the rituals by keeping clean, doing regular prayers, following a vegetarian diet and fasting while remaining celibate.
Thaipusam is observed by Tamils in India, Sri Lanka, Southeast Asia notably in Malaysia, Singapore, and Indonesia. It is also observed by other countries with significant Tamil diaspora like Fiji, Mauritius, Seychelles, South Africa, Canada, the Caribbean countries including Trinidad and Tobago and Guyana, and in countries with significant Indian migrants like the United States. It is a public holiday in Mauritius, select states in Malaysia and in the Indian state of Tamil Nadu.
Etymology
Thaipusam is a portmanteau of two Tamil words: Tamil month of Thai and the name of the star Pusam, denoting the day of occurrence of the festival.
Theology
According to the Kanda Puranam (the Tamil version of the Skanda Purana), three asuras (a race of celestial beings) Surapadman, Tarakasuran, and Singamukhan performed austerities to propitiate the Hindu god Shiva. Shiva granted them various boons which gave them near-immortality and the ability to conquer the three worlds. They subsequently started a reign of tyranny in their respective realms and oppressed the celestial beings including the devas and other people. The devas pleaded Shiva for his assistance to put an end to the reign of Surapadman and the asuras. In response, Shiva manifested five additional heads and a divine spark emerged from each of the six heads. Initially, the wind-god Vayu carried the sparks, but the fire-god Agni took possession of them afterwards because of the unbearable heat. Agni deposited the sparks in the Ganga river. The water in the Ganga started evaporating due to intense heat, and so the goddess Ganga took them to the Saravana lake, where each of the sparks developed into a baby boy. The six boys were raised by handmaidens known as the Kṛttikās and they were later fused into one by Parvati, thus giving rise to the six-headed Murugan.
Parvati granted him a divine spear known as the vel. Murugan was accompanied by Virabahu who served as his commander-in-chief and eight others, who were sons bore by nine shaktis who arose from the gems of the broken anklet of Parvati, when she ran from her seat due to the heat generated by the sparks emanating from Shiva. Along with the armies of the devas, Murugan waged war on the asuras. Murugan split Surapadman into two with his vel and the two halves transformed into a mango tree and later into a peacock and a rooster. Murugan adopted the peacock as his mount and took the rooster as his flag. Thaipusam festival is celebrated to commemorate the victory of Murugan over the Surapadman.
Murugan is a deity associated with yogic discipline and austerities in Hinduism and is regarded by his adherents to be capable of offering mukti (spiritual liberation) to those who venerate him.
Occurrence
Thaipusam occurs annually and is celebrated on the full moon day in the Tamil month of Thai on the confluence of star Pusam.
