On the full moon day of the tamil month of Karthikai, the Hindus celebrate the karthikai Deepam. On this day, there is special celebration at Thiruvannamalai in South India. Lord Arunachaleshwara is the presiding deity here. Of the five holy shrines of Lord Shiva, the 'Pancha bootha kshetram', Thiruvannamalai is the 'Jyothi Kshetram' where the Lord is personified as the divine light combined with brightness and wisdom. Arunachala Hill is the place that represents the fire element and the Lord is Tejo Lingam here. When the huge beacon is lit on the holy hill on the Karthigai Deepam day, people worship it, loudly chanting “Harohara". The esoteric meaning is that one who sees the light of lights that is burning eternally in his heart through constant meditation, attains immortality. The light on the Arunachala brings the message to you that Lord Shiva is self-effulgent and is the light of lights. The lighting of the Maha Deepam will take place simultaneously with "Deeparadhanam" to the five deities in the temple at the foot of the hill. There is another legend as well. Lord Murugan is also called Karthikeya. Lord Muruga took the form of six babies in a lake called "Saravana Poigai". On this day, Parvathi (his mother) united all his six forms and so Lord Muruga has six faces. Special pujas are performed to Lord Muruga. தாமரையில் பூத்து வந்த தங்கமுகம் ஒன்று தண்ணிலவின் சாறெடுத்து வார்த்தமுகம் ஒன்று பால்மணமும் பூமுகமும் படிந்தமுகம் ஒன்று பாவலர்க்குப் பாடம்தரும் பளிங்குமுகம் ஒன்று வேல்வடிவில் கண்ணிரண்டும் விளங்குமுகம் ஒன்று வெள்ளிரதம் போலவரும் பிள்ளைமுகம் ஒன்று ! On that day, in South India, people place rows of earthern lamps in front of their houses in the evening and worship the Lord. Bonfires are made in front of the temples in the evenings. It is said that Lord Shiva burnt the chariots of several demons who were torturing sages. This bonfire symbolises this legend. Eradicate the three impurities, namely, egoism, selfishness and delusion. Burn the mind, senses and desires in the fire of knowledge of the knowledge of Shiva. Attain full illumination and behold the light of lights, which illumines the mind and the intellect. This is real Karthikai Deepam. Love & regards, Chithra.
