wacky jacky:
i wonder if others have noticed anything systematically accompanying it, such as the headache and dullness/tiredness that i experience?
Hi wacky jacky,
Sorry for the delayed response. I'm glad the thread is helping you. Kundalini experiences can be everything up to terrifying, especially if you haven't awakened it via shaktipat, with the guidance of a yogic guru. I awakened mine in a car accident via near-death-experience and i was definitely not ready for what followed!! It can be really frustrating and destabilizing. So what you are describing sounds pretty natural, and i would encourage you to read about kundalini. Wikipedia is a good start, and there are some great books out there. Lilian Silburn's "Kundalini: The Energy of the Depths" and Swami Kripananda's "The Sacred Power" really helped me. I also highly recommend William Bodri's "The Little Book of Hercules", in fact, i recommend that more highly than those first two.
The headache and fatigue that comes from the body motions have happened to me too. It passes. In my case, opening up took years, and during those years i would have intense periods of calm, interspersed with intense periods of kundalini blasting through everything that stood in its path. I have had swoops, shakes, violent spasms, been pinned to the floor, and worse.

Now I have almost no chronic discomfort due to obstructions, i am calm and blissful, and can access rarified states of consciousness with relative ease. The journey deepens and deepens, and the initial pains of kundalini's cleansing give way to the wonders of the mystical path in time. In fact, it has been said that there is really no stopping the progress of kundalini, and if you are meditating in stillness regularly, it will only happen faster that you awaken to the samadhi states that having open channels and awakened energy enables.
Let everything pass as it arises, and it will give way to deeper layers of the onion. Keep sitting, and studying, and your physical sensations will pass with time. Blessings to you!
