The wild dance of Kundalini, when She wishes to move through the body is—in my experience—not something that can (necessarily) be activated or controlled by meditation technique. The expectation that meditation, or any psycho-spiritual process can, in a step-by-step linear fashion, activate Kundalini gets in the way of allowing Her initial awakening in our spine (and rest of the body).
A “tight” mindset around meditation techniques and spirituality in general acts as a binding agent around Kundalini…and so She remains “asleep” in the spinal centers, held captive by the “straight-jacket” of our outward focus and disconnection from primal energies held in the spinal centers.
As mentioned previously, I believe meditation technique, although it cannot necessarily connect us with Kundalini, it can be helpful after we’ve made the connection…when attuning to the exquisitely subtle aspects of Her vibration. But when She wishes to move/dance wildly in the body, technique has no meaning or use…there is only getting out of Her way!
