Hi Magne,
Thanks for the link. I just wanted to add a warning:
Sites like this are produced with little understanding of what kundalini is, and the role that kundalini plays in the spiritual evolution of human consciousness. If you study the site carefully, it makes out that kundalini is essentially a bad thing that is an unfortunate by-product of misguided meditation techniques and eastern religious practices. Such a view gives a very misguided interpretation of what kundalini is about, and leaves the impression that kundalini energy is something to be avoided. Actually the awakening of kundalini is something that must happen in the journey of every spiritual person at some point, and in some fashion, from whatever background they come. No kundalini... no enlightenment.
People who author sites like this are doing a good job in that they are helping people who are undergoing a premature kundalini experience, and possibly suffering as a consequence. But they are giving essentially very misleading advice that will not help those people move forward spiritually once the fire calms down.
