Diebert,
Cool to see you're interested in it.
In my understanding, kundalini is a purifier of a person's
"baggage". Emotional trauma is tied to a person's physical body, and in order to have that non-attached philosophical attitude, any emotional problems need to be cleared up...including any latent impressions (things that don't show themselves most of the time, but you can tell you have them because of patterns in behavior or feelings). The body needs to be back in the emotional state of a newborn...absolutely no stored stuff that gets in the way. Then there's some room for the truth.
When the kundalini rises, it's said to purify the "72,000 nadis" (energy channels). I don't know if there are actually 72,000 nadis, or what yogini had the audacity to actually sit there and count them...but it can be simplified to: kundalini prepares your body for enlightenment. Kundalini is not enlightenment itself, because many people who've had awakenings are still stuck in their delusions.
They say that a premature awakening of the energy causes a lot of problems, however according to most traditions, the rising of the kundalini in the sushumna nadi is a necessary prerequisite to realization. So if someone does want to awaken the kundalini energy, they should purify the body...the Hatha Yoga Pradapika says to do alternate nostril breathing, in addition to alterations of diet. Also, the author of
http://www.aypsite.com says that reaching samadhi in meditation is a prerequisite as well. His method for having an easy awakening of the energy is to do "spinal breathing"...check it out if you're interested.
Mainly, I think the most important thing to take from all of this is that in order to be immersed in the truth, you have to
fully be rid of delusion.
And in case you're wondering about my experience on the matter, I don't have much. I only know enough to know that I trust the sources I read from. If I ever come to know more due to my own experience, I'll let you know, if you would like.
