There are lot many books in stores about Sri Chakra worship. Worshipers do hear about Navaavarna, Nityaa Devis and all. But there is no other authentic book describing about each of the Navaavarna and mapping the same with Sri Devi Khadgamala Stotram and all. More specifically there is no other book to talk about the construction of Sri Chakra and explain the nuances about the each of the triangle, square, circle, etc. This book is unique in this regard.
