This book has live experience of not one but two Guru's Swami Sivananda & Swami Satyananda and aptly explains the advanced stage of Samadhi in detail.
For the enthusiasts who are initiated or are advanced students of Raja Yoga or alike, into meditation, this book explains what to expect when into stage of Samadhi and also the different stages of it.
Its a book beyond the ordinary realm of life and truly a blessing since the untread charters cannot be traversed without an enlightened Guru.....
Long long time ago at a book fair i had seen the book, looked at it, was attracted but could not understand what was it all about. So it was a long wait till it surfaced again on flipkart pages.
Now i understood why the book had a photographic memory in my mind.
Its a must read if you seek a life beyond worldly things.
