Yeah, Kundalini is a commonly misunderstood thing... It is very powerful, and if awakened too early, it can wreak havoc. It's not a "good" thing. It's a neutral awakening of power that brings a lot of stuff to the surface.
Last summer I had some kundalini energy risings. I was doing some sexual practices that were awakening it, as well as some psychedelics. There were a few times where I thought I was dying. It's powerful stuff! I prefer now to let kundalini awaken naturally, on its own accord, rather than trying to summon it up. If you let it be, it will arise when you are ready. Dangerous stuff.
It all sounds hokey or lofty until you've experienced it for yourself.
