I should also add that there appears to be some genuine benefit gained from using HS over a period of time. But it probably has more to do with the fact that these people are growth enthusiasts and they have also spend many an our in meditation/contemplation. So of course they have gained something.
Now, I don't want to make out that everyone making a buck or two is dubious but there is an old saying: "follow the money trail". The marketing behind the HS is clever very clever. But its all to easy to keep saying that the changes will happen in level 4, or 6 or 8 or that you have to buy some expensive "LPIP" course to get somewhere in life. Wake up people! the answers to lifes questions are available everywhere and they don't necessarily cost so much!! Good luck to you all
