Though this books seems was published in 1997 (and, I have 2007 second revised edition with me), I was unaware of its existence till I saw a reference in one of Ram Guha’s articles. It is a must-read, especially if you are interested in the poetry of Mira, Andal and Akka Mahadevi. I especially liked the sections of the book on Sangam literature, Budhdhist and Jain literature and Veerashaiva movement — obviously because of my own interests. Strongly recommended. If I have any quibble, it is that some of the pieces are a bit dis-jointed and there are a few minor mis-prints and mistakes.
