The Tamil Calendar month of Aadi is considered sacred in the Hindu Tradition. And when certain special stars or condition fall during this month, they are also celebrated with religious vigour – for example, Aadi New Moon Day (Amavasai) is considered to be sacred for paying obeisance to the departed ancestors.
Similarly, when one of the 27 stars, Pooram (Tamil) falls in Aadi, known as Aadi Pooram, it is considered as sacred and special pooja are performed in most temples. (It is a grand occasion in the Sri Villiputhur Andal temple as it is the birthday for the deity Andal. who was an ardent devotee of Lord Vishnu and married Him).
Aadi Pooram was celebrated today in a grand manner in Thiruvannamalai temple today. A special ‘Theerthavari’ (sacred water being showered on the deity of the Lord) was performed in the Sivagangai Sacre Pond located in the 5th Corridor of the Thiruvannamalai temple. Earlier, the deity of Parasakthi Amman was taken to the Theerthavari Mandapam (Hall) offering Darshan to the devotees.
