Karthigai Dheepam (Lord Skandha)
Karthigai dheepam festival is in the month of Karthigai (November-
December) which is observed in every home and in every temple. This occurs on the day when the moon is in conjunction with the constellation Karthigai (Pleiades) and purnima.
This constellation appears as a group of six stars in the firmament in
the shape of a pendant from the ear. As usual, many legends and lyrical poetry have grown round this star. The six stars are considered in indian mythology as the six celestial nymphs who reared the six babies in the saravana tank which later were joined together to form the six faced Muruga. He is consequently called Karthikeya the one brought up by the Karthigai nymphs.

Lord Siva appeared as a huge flame of light before Lord Vishnu and Lord Brahma (hindu gods), who each considered Himself supreme and said that the matter could be tested if the two could search for their Lord Siva`s Head and feet. Lord Vishnu took the form of a (varagar)boar and delved deep into the earth, Lord Brahma that of a (Annam)swan and flew into the top, Lord Vishnu failed in His search and returned. But Lord Brahma, chancing upon a piece of `thazhambu`, a flower learnt from it that it had been floating down for thirty thousand years from Lord Siva`s head. He seized upon this and claimed to Lord Siva that he had seen the other`s top. Lord Siva realized the falsehood and pronounced that there would never be a temple for Lord Brahma in this world. He also interdicted the use of the flower thazhambu in His worship. Lord eswaran(siva) appeard as a flame, this day is called Maha Dheepam
