The days of secrets are over, it is too easy now to see and debunk the charlatans, and there are plenty of folk who know how to do this IS/aiki stuff who are willing to share what they know.
Hmmmmm.. I don't know if the days of secrets are over. I have things that I reserve for people who I think are ready for them. Over the years I found that if you start showing bells and whistles along with the basic things, the gung ho guyz will all start trying to do the bells and whistles and their basics don't develop... so I try to separate different levels of information to different levels of people. That would be "secrets".
