E-Book about Sithars in English and Tamil

Siddhars (Tamil: சித்தர்) are saints in India. There are 18 Sidhars and all the informations are not properly consolidated or put together in an organized way. I tried (still am adding additional details) to put everything that I have, collect from various other sources and created this E-Book. If you need the Printed Version, Pay only Rs.250 (Including Postal Charges)
