He Gelal,
Aunt Clair's descriptions of how to raise Kundalini are exactly what they are. She has no other way of explaining it. In other words, it would be similar to a Catholic trying to explain prayers to Saints to a Buddhist. I would recommend reading the links that she gives to better understand, or Google "Hermetic Magick". If you read some of the background of what she does, then you will understand it better.
