It sounds absolutely absurd, if you ask me. When broken down to its basics, they claim that a package of "frequency" CDs will enable an increased state of relaxation and calm, and establish a deeper sense of the "Divine". Hell, I can achieve that sort of awareness listening to my favorite bands and classical composers. I'm under the suspicion that they use the technical jargon to attract the gullible. The fact that they use the building blocks of our being (DNA) as a method to change reveals a rather malicious hook... it appeals to the especially desperate seeking a way for improvement and change.
This is a cynic's playground. Nonetheless, read in between the lines VERY carefully.
