| Vijayaraghavan was well versed in Sanskrit and Tamil, the only son of famous upanyasaka tirukkannapuram Pattappa Swamy. Pattappa Swamy, to this day, is considered to be one of the most important personalities in sri vaishnavam or [[ramanuja]] sampradayam in the 20th century. Vijayaraghavan was a close friend of [[André Weil]]. He served with him in [[Aligarh Muslim University]]. He later shifted to [[University of Dhaka]], protesting Weil's firing from AMU.<ref>M.S.

The author's title is Andera and she believes it sounds fairly great. I am currently a journey agent. It's not a common thing but what I like performing is to climb but I don't have the time recently. Mississippi is the only location I've been residing in but I will have to transfer in a yr or two.
