When I was going through my awakening, I found this book to be the most helpful in helping me understand the process.
This book was written by someone that has attained enlightenment in this lifetime.
There are many other teachers like him that have written books such as Eckart Tolle, Mooji, and Tich Nhat Hahn, but most don't describe the actual awakening process prior to enlightenment in the depth that Adyshanti does.
This book helped me have a very clear understanding of many of the different and unusual experiences I was having caused by awakening.
I have read this book MANY times and to this day I consider it an invaluable source for me.
