This is a very special occasion for me. The 100th post of Karka Nirka blog. And I have decided to give a treat to all my readers. Hence a guest post and there no better person to write on this Blog than Dr. N.Kannan. Dr.Kannan is the Director of Tamil Heritage Foundation and also a poet and an author(http://www.e-mozi.com/articles/biosketch.html , http://freenet-homepage.de/bliss/bio_english.html) . To me he is one important person associated with this blog indirectly. I post my blogs in MinTamil group where Dr.Kannan is a moderator. When I started posting in MinTamil at times I would get brilliant insights from Dr.Kannan which never occured to me from Dr.Kannan. He and other members in MinTamil have posted valuable comments and reviews on the post and have encouraged me to write more on Sangam Tamil. I couldn't find any better person than Dr.Kannan to be the person to be part of my 100th post. Dr.Kannan asked me wether he could write in Tamil and I gleefuly accepted since I thought atleast the 100th post in a blog which speaks the greatness of Tamil to be in Tamil. For non Tamil readers, I will translate this work soon. Finally I would like to thank Dr.Kannan for accepting to write a guest post for me in his very busy schedule.
