Recently there was a talk on Alwars at our Ashram. I was not fortunate to be there, but was told of the event by my uncle. I do not have the transcript of the talk(s), nor details of the event, but will post it, if and when, I do get them. In the meanwhile, here is a link to a webpage on the Mudhal Alwars (Poigai Alwar, Budat Alwar and Pey Alwar).
