It is essential not only for human life but also for animal life. The substance is salt. Gandhiji started the crusade for national liberation by salting that water, air and light should be available free of cost to the poor people of India. You have to write a novel about going to the salt flats. " Before I finish writing a novel the votes for such impulses will probably fall on my ears to launch the next attempt. This time I will not even say that it is just a vote. It is very stressful. So, I traveled to Thoothukudi with my finished novel 'Alaivaik Karaiyil'. In Tamil Nadu, salinities extend from Chennai to the coast. But the coastal areas of Thoothukudi produce a large quantity of quality salt at a very low cost, as the humid air and solar heat required for salt production are available for ten consecutive months of the year.
