Thank you for the information which refreshes the mind. I have a doubt or I would like to know whether the Kalasams have embedded lightning arrester or something else to serve the purpose. If they do not have, there is a possibility of many gopurams having been affected or damaged. Though top damaged temples which abound only in TN, are seen have they been reported as such. Moreover, the intensity and frequency of the lightening is more over western coast (during onset of s.w. monsoon) and it is less pronounced during n.e. monsoon. To add to information, if science can only capture one lightening live, it can run the entire energy system including lighting, motive power,etc. for at least 15 minutes in the world. The power of nature indeed.
