And your wondrous alternative... Perhaps an ebook for only 39.99?
Talking about a method, yet revealing nothing about it means either:
1) There is no method. You may or may not be selling it, but it actually doesn't exist.
*Conclusion: practice or commerce, 100% obfuscation, 0% content.
2) There is a method. It's tacky, expensive, and requires some serious brainwashing to get people to buy into it. However, to keep their attention, you use their curiousity, attracting the weak with a veneer of mysticism, and "rewarding" them for their attention step by step.
*Conclusion: Pavlov's dogging. AKA SCIENTOLOGY. Or the 100500 other cults, organizations, political parties, and direct sales companies that borrowed the method.
3) There is a method. It's an ebook for only $39.99.
*Conclusion: 100% obfuscation, -$39.99, some degree more content than option 1. If relevant content is present, it is very likely directly copypasted by pieces or plagiarized entirely from some classical source.
...now, which will it be?
