To be fair to the book, it needs to be read first before undergoing the course of Inner Engineering offered by Sadhguru's Isha Foundation. In my case, I underwent the course first and then read the book and hence some parts of the book seemed repeated (as I had already watched the corresponding videos). In any case, a beautifully written prose with extreme fluidity and it is as if Sadhguru is talking and not as if you are reading a book. Some parts of the book are extremely invaluable like when he talks about the chakras, the Kundalini, rebirth, karma, etc. Definitely worth a read and a book to own.
