Since most of the DDs (82 of them) are in TN, we will start off with the DDs in this part of the country.. based on the break up that I gave in my earlier tweet, we will start off with the Chozha naatu DD's which are around 40 in number..

The first and foremost DD not only for Chozha naadu but for all DD's is Sri Ranganathaswamy Temple at Srirangam.. I will attempt to give a quick overview of how this temple referred to as "Boologa Vaikuntam" or Heaven (Vaikunta) on earth came to be..

According to the Sriranga Mahathmiyam, Lord Vishnu in the Sri Ranga Vimanam sprang up from the depths of the milky ocean as a result of the tapas of Brahma, carried by Garuda, his mount with Perumal resting on Ananthan or Adi Sesha 2/N

Brahma was informed that Lord Maha Vishnu would appear like this in 7 other places on earth - Srimushnam, Venkatadri, Saligramam, Naimisaranyam, Thotadri, Pushkar and Badri but of all these places Srirangam would be the earliest

Brahma was also informed that Lord Maha Vishnu would appear as a Swayamvaktha ie in his original form as an idol at these places.. Brahma then carried the glittering Ranga Vimana and installed it on the banks of the Viraja river..
