Why karteega deepam is so important?

The legend says: Once Devi Parvati, closed the eyes of her consort Lord Siva playfully in a flower garden at their abode atop Mount Kailash. Although only a moment for the gods, all light was taken from the universe, and the earth, in turn, was submerged in darkness for years. Parvati performed penance with other devotees of Siva, and her consort appeared as a column of brilliance of trillion suns shining flame of fire at the top of Annamalai hills, returning light to the world. He then merged with Parvati to form Ardhanarishvara, the half-female, half-male form of Siva. The Annamalai, is called red mountain. This mountain lies behind the Annamalaiyar temple, and is associated with the temple of its namesake. The hill is sacred and considered a lingam, representation of Siva, in itself. The Lord Siva appeared as on Karteegam star and month in bright full moon day so, this day is called karthikai maha Deepam a symbol of lighting maha Deepam on Annamalai mountain...
