What's truly funny (or sad) is I know they guy that won that auction. I know he honestly believes in and owns a bunch (and I mean a bunch) of Shakti products. I can't say anything at all from my personal experience, but his opinion is that the more you have the more difference it makes. The effects are cumulative apparently.
I'm not a believer on faith when it comes to this kind of stuff, in general, but perhaps there's something to it. Hell, if it works for you then you shouldn't let anyone else talk you out of it. We're all crazy anyway.
Enjhoy,
