I have no doubt that Erbe sentanu has done well on his book. If you read the book “THE SECRET”, the book “KUANTUM IKHLAS” is the key to the secret. The book comes with a CD to upgrade our brain. Yes, with the technology he call “digital prayer”, we can access our subconscious mind instantly, and give information into it. As we know in the other book, our subconscious mind affect our life the most. There are ways to access it, and I find that the digital prayer technology is the most effective. I highly recommend you all to buy this book and upgrade your brain. It’s effective on me, and it’s your turn to try it!
