A popular event performed a few years ago is the Sri Subrahmanya Sahasranama (1008 names of Subrahmanya) Archana. A Sahasra namamala, a garland of gold coins on each of which one of the 1,008 names of the Lord was inscribed, was made and offered to the deity. Devotees from far and near in large numbers participated in this holy and pious act.
Here also pilgrims carry Kavadis to the shrine and abhishekams are performed to the idol on behalf of the devotees. Bathing of the deity in holy ashes, known as “Vibhuti Abhishekam” is a feature here as in palani temple, and in that Abhishekam the idol has a very captivating and awe-inspiring aspect.
Krithigai is an important festival celebrated in the Tamil month of Adi or Aadi. The festival is dedicated to Lord Muruga or Subrahamaniya. Incidentally, the festival is also referred as Aadi Krittika, Kirthigai, Kritika and Krithika. The festival is celebrated with fervor in the Murugan Temples in Tamil Nadu.Krithigai in some regions is celebrated to symbolise the victory of good over evil, when Murugan slew the demon Surapadma.

Navaratri is a festival dedicated to the worship of the Hindu deity Durga. The word Navaratri means 'nine nights' in Sanskrit, nava meaning nine and ratri meaning nights. During these nine nights and ten days, nine forms of Devi are worshipped. The tenth day is commonly referred to as Vijayadashami or "Dussehra" (also spelled Dasara). Navaratri is an important major festival and is celebrated all over India and Nepal. Diwali the festival of lights is celebrated twenty days after Dasara. Though there are total five types of Navaratri that come in a year, but Sharad Navaratri is the most popular one. Hence, the term Navaratri is being used for Sharada Navaratri here.
The hallowed full moon day in the month of Vaikāsi, under the Visākam star is the Vaikāsi Pournima also termed Vaisāki Paurnima. The Vaikāsi moonlight floods the world with a glorious effulgence making the over arching sky infinite and vast. In our tropical skies, the moon, 'slowly and silently walks the night in her silver shoon.' The transparent clouds seem to salute her as she moves unhurriedly. This is indeed Nature's magnificence manifesting itself with an overwhelming grandeur. And with this mysteriously beautiful soft light of sanctity, comes a hush, deep and strange reminding the Hindus and Buddhists of the significance of this sacred day.
Navratri commences on the first day (pratipada) of the bright fortnight of the lunar month of Ashwin. The festival is celebrated for nine nights once every year during the beginning of October, although as the dates of the festival are determined according to the lunar calendar, the festival may be held for a day more or a day less.
Skanda Sashti is observed on the sixth day of the bright fortnight of the Tamil month of Aippasi (October – November). This day is dedicated to the second son of Lord Shiva – Lord Subramanya, also known as Kartikeya, Kumaresa, Guha, Murugan, Shanmukha and Velayudhan, who on this day, is believed to have annihilated the mythical demon Taraka. Celebrated in all Shaivite and Subramanya temples in South India, Skanda Sashti commemorates the destruction of evil by the Supreme Being.
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 therefore called Karthikeya, the incarnation of lord Shiva as his second son after lord Ganesha. Stories tells lord shiva created Muruga from his 3rd eye of six primary faces (Tatpurusam, Aghoram, Sadyojatam, Vamadevam, Eesanam, Adhomukam). Stories tells the six forms made into six child and each of them brought up by the six Karthigai nymphs and later merged into one by his mother Parvati.While merging he also formed into a six faced (Arumugam and twelve handed god. The Lord muruga is also portrayed with his six plays and worshiped with six names.As the six nymphs helped in growing the six child, lord shiva blessed immortality to the six nymphs as ever living stars on the sky. Any worship performed to this six stars is equal to worshiping lord muruga himself. They are worshiped by lit up with rows of oil lamps (Deepam) in the evening of the festival day around the souses and streets. Karthikai Deepam is also known as Kartikeya, or Muruga's birthday.
The Kavadi Attam is the ceremonial sacrifice and offering performed by devotees during the worship of Murugan, the Hindu God of War. It is often performed during the festival of Thaipusam and emphasises debt bondage. The Kavadi itself is a physical burden through which the devotees implore for help from the God Murugan. Generally, Hindus take a vow to offer a kavadi to the deity for the purpose of tiding over or averting a great calamity. For instance, if the devotee's son is laid up with a fatal disease, he would pray to Shanmuga to grant the boy a lease of life in return for which the devotee would take a vow to dedicate a kavadi to Him.
This month is special because the Uthiram nakshatram coincides with the full moon. This full moon signifies the marriage of Parvati and Parameswara (Lord Shiva), Murugan and Deivanai, and Aandaal (also known as Kothai) and Rangamannar took place. On Panguni Uthiram, Narayana marries Komalavalli Naachiyar and give his Kalyana Kola Seva to his Bhakthas. Again, Valmiki's Ramayana says it is on this day and star that Sita's marriage with Rama was celebrated. From Brahmanda Puranam we learn that on Panguni Uthiram every holy water joins Thumburu teertha (also spelt as Tirtha), one of seven sacred tanks in Tirupati Tirumala.
