Hi, hope4now!
I had a kundalini-experience for several years, starting in 2005. It increased in intensity for the first 6 months, but started waning after some years and was gone after about 10y. Which was a big loss to me, so-called "normal" life has been flat and boring ever since. So after grieving it for a while, I have been on my way back to this "real life", as I perceive it, with some outside help. Seems I am back there now, or at least to a high enough degree of energy for my taste.
I don't have a clinical diagnosis of PTSD, but did (and to a minor extent do) have some trauma to work through. And it doesn't necessarily stop with memories from this life, and I also seem to have taken on trauma from other people's experiences. (Unfortunataly I don't have enough defense mechanisms against other people's emotions and energies.)
One of the biggest traumatic memories first came up in the first year of kundalini, first a vision of the scene and only months later the emotions attached to it. I think kundalini accelerates the clearing of these things.
I can highly recommend EFT (emotional freedom techniques) for releasing trauma, whether with kundalini or without. Did bunches of it at that time. There were times in my life I don't know how I could have coped without it, with an overwhelming amount of memories and emotions flooding me. I especially like about it that I can use it as a self-help-tool, to be used anytime I need it.
Little caveat: It seems that most people with kundalini can do EFT without a problem, i.e. without increasing the energy flow to an unpleasant extent, but I have met 1 person with an active kundalini, who had to be very careful with it.
There are some EFT-ressources on PTSD on the internet
Even though I am not a vet (my grandfather I lived with was, though), I found it helpful to use some of the videos and transcripts for war-related PTSD. In a way the inner reaction to different traumas is not so different.
And of course there is also material directed at other types of trauma available for free on the internet.
So, how is you kundalini-process going after some years?
