This should be a textbook and literally be taught to everyone on Earth!
Format: Kindle
I was absolutely enthralled the entire time reading this book. I have read books on Lucid dreaming and have been fully lucid a couple of times so far. Astral Travel has definitely been on my list of things I want to learn. This book is so incredibly detailed in every aspect on the subject of Astral Travel. It has inspired me to want to put all my energy into successfully controlling my Astral travels. She lists common misconceptions and dangers to be aware of. She also has detailed outlines of how to journal properly, as to que your subconscious mind of how important it is to you on your conscious level. I always wondered what the difference between Astral travel and Lucid dreaming are and that is also explained in detail. She has so many fantastic methods to apply as you attempt to separate your Astral body from your physical body. I would absolutely 💯 percent suggest this book to anyone looking for valuable information and insight into the art of Astral Travel.

Easy read
Format: Paperback
I really enjoyed this book. It was very easy to read and understand. It gives different techniques you can try and helps you understand why you shouldn't fear traveling. This is a book I will reread for reference. I haven't successfully AP yet from reading this but it has gotten me to lucid dreaming, which I wasnt able to do before.

Great Astral Travel Guide
Format: Kindle
Astral Projection for Beginners is the best Silvia Hill book to be released to date. The guide walks the reader through the entire subject. Filled with great tips from breathwork to hypnotism and many solid methods for achieving astral travel , this book is a must for anyone interested in this otherworld topic. I have the paperback in my library, but this book is available on Amazon Kindle Unlimited as well. Pick it up and go. Enjoy!
