Thank you! I bought the same book in soft cover about 10 years ago. It's a fantastic book and the sort you like to have in print for reference, but I'm not so inclined to haul around the big heavy books anymore. Nice to have the digital edition.
Good for you...you've known it long enough and read about it.
It is indeed a very enlightening book. It explains the very basic of chakras especially the root chakra which most of neglected. It is also through this book I've understood that proper balance of the chakras is essential for both manifestation and enlightenment.
It's about the flow of energy back and forth without blocks. It's easy as it may sound, but to achieve it, practice is a requirement.
