I bought this Kindle book to accompany the video talks by Sri Sri Ravi Shankar presented as part of my yoga teacher training.
Without this book (which is as close to a word-by-word transcript of the talks as is possible to get), I would have had difficulty understanding the imperfect audio technology of the talks coupled with Sri Sri Ravi Shankar's accent. So just read the book? Well, no. Without the videos, I felt the book would have lacked something vital - but I don't know what would be, exactly.
This book was extremely important in my yoga teacher training journey - no, more than extremely - PRICELESS.
And in gratitude for that gift to me, I give this book 5 starts.
