Thank you for taking the time to key in your replies, everyone! 
@Alex, Anant, DvD : I agree with all your scepticisms concerning the request as my initial reaction was the same. And my initial thoughts were just that - He should access it via my blogs; online. The only thing that's prompted me to go ahead with it then - was a quick search I did to find out more on him, just out of curiousity - and, I came to know he is a senior citizen and a retired governement employee.
Since my blog is about travel with a concentration on my yatras or pilgrimages, chances are that he might be interested in reading it but is having difficulty accessing it online. Perhaps it's more comfortable for him to read it in paperback form after printing. Moreover, his e-mails sound genuine to me and my gut feeling tells me to trust, hence I decided in favor of sending over my blogs to him.
Not sure if this is the thing to do otherwise but considering what I gauged, seems pretty harmless in this case ...
