This is an absolute must have if you either have attended or plan to attend the Kalachakra initiation. It has the text of the actual previous initiation given in Wisconsin in 1981. When I attended the Bloomington initiation in 1999, we followed the text almost word for word. Sometimes it's hard to understand the translator over earphones, but with book in hand, I had no problem at all. And it's essential to read ahead of time so that the experience has meaning. In addition, this book has been a friend and companion in daily practice since the initiation. (If you're new to the process, part of what you sign up for is to practice six times a day for the rest of your life.) The text has the actual daily practices as well. Hopkins' introduction is the equivalent of a college course. I thought, arrogantly, that I was prepared by having read a few books on Kalachakra and having practiced other deity yogas for several years. Only after studying did I find how much I have to learn. I've read this book many times, and will continue to do so. It takes on more sophistocation as I grow in my practice. My usual reaction on re-reading is like, "Oh, no, that's what I vowed to do--wish I had realized it at the time."
while in india i got the book from mlbd.i read it once,then again and again i read this book.i also practised it,and got benefits in improving the system of life.based on my experience i can say,it is very usefull for those who wish to go on spiritual path,it is also usefull for common people struggling to get rid of mental stresses etc..,
