Re: Indispensability of Tamil?
Tamilians really love their Tamil. :-)
I have exactly the same problem. I suspect that more translations into English will gradually become available, but the writings of the Alvars will probably never feel quite right when read in English. In the mean time, there are still plenty of works translated into English, and while some of the free E-books online will require that you learn a few Tamil words, this can be done without too much effort and will be worth it.
I do know that the Sri Vaishnava temple I attend is mostly attended by Telugus, and I doubt many of them know Tamil. It doesn't stop them from participating.
