I was very disappointed in this book. It felt very redundant and didn't seem to progress much.
All you SRF students can relax. Although from scanning this book, the Energizing Exercises, Hong Sau and Om were apparently sent out with these very first lessons, those techniques are not in this book.
Long ago I completed the SRF lessons up through the highest Kriyas, so I ordered this book to see what all the fuss was about. At least at one time these lessons were authorized by Yogoda Satsanga Society which preceded the Self-Realization Fellowship name. These lessons are probably the old lessons sent out to devotees by Amrita.
Each lesson is preceded by this statement: "This sacred lesson is meant only for the devoted Yogoda student who would untiringly and unceasingly, seek God until he finds Him." So indeed these lessons were meant to carry a very special spiritual vibration.
This edition is not the first time the lessons have been made public. Kessinger Publishing printed these lessons in August 2003. The book is sold through Amazon. The lessons are apparently a scan or photocopy since the font is of an older type, lacking the perfection of newer computerized fonts.
And SRFers--Don't you think that Yogananda could have prevented the publication of these lessons if he'd wanted to? Let's have some reality testing. Perhaps the publication of these older lessons is meant for an introduction to the superior SRF lessons of today.
The lessons are fun to read, but less polished than the lessons SRF now sends to students. The very first lesson in the Super Advanced Book is a lesson that doesn't appear in the regular lessons until the advanced Kriyas are sent out. The first lesson is on the spinal passageway and St. John's revelation. I have no idea why this lesson has been moved far ahead to the advanced Kriya lessons by SRF.
Like many decisions of SRF, we don't know if they are Yogananda's thoughts or the well meaning decisions of those who are in charge of the organization. When Yogananda first wrote these lessons, he didn't waste any time getting to the point. Of course now knowledge of the Kundalini and related topics are in the popular domain. Nevertheless there are many false ideas of what is meant by Kundalini. Yogananda clears up these misunderstandings.
The current SRF lessons are better organized and have better editing. If anyone wants to learn Yogananda's Kriya technique I'd advise subscribing to the regular lessons. A shorter path to Kriya is offered by Ananda in Nevada City, CA. The vibration is somewhat different there. Each student has to choose the path which feels more comfortable to him or her.
