Hello Bluelighters! This is my first post here, in fact I made the account because of this post!
To the OP, I of course cannot condone the desire to jump beyond the initial steps of spiritual practice into the various states or modes of consciousness that produce all manner of informational and visionary experience, at least not without a lot of background and perhaps a bit of training in formalized systems through a guru or master. Ancient knowledge is still alive in various traditions on how to safely navigate the spirit world as I'm sure you know. But like me you are probably not in a good place to do such seeking right now.
Beyond that I'd like to share a brief story of my experiences. I have had kundalini or spirit awaken in me spontaneously, from what I can only speculate is a combination of factors in a perfect storm so to speak:
1. A surgical procedure that damaged by guts and perhaps my spine, while also inducing a near death state of drug induced coma during the procedure.
2. A hypersexuality notable in potential shamans
3. Intense mental faculty that started as linear, reductionist and analytical, but was then blown open into the free associative state by 3 years of heavy marijuana usage during the first years of my adult life (18-21)
4. Possible atrological influences of the sign of the serpent bearer, being born on the 334th day of the year
5. The re-emergence of the ideas of 'magic' in the media such as movies and videogames that inspires my scientific mind
6. My desire to be immortal in the light of my comparison of world religions being of the same spiritual origin at their core, creating a somewhat secular or deistic worldview bordering on pantheism or pan-deism, in which everything is from a Source and ultimately understandable by mankind.
7. My personal history of learning from the mistakes of my father after his death when I was 12 that showed me how I was responsible for my actions and my emotional reactions.
8. The possibility that I am susceptible to kindling or epileptic activity in the frontal lobe. Not confirmed and of course possibly a side effect of stress instead of inborn propensity for epilepsy. Had a few minor 'seizures' and visual/verbal aphasia, but no loss of consciousness and no violent spasms until my experiences began, and even then it was from my spine not my brain this energy arose.
All of this came to a head one day while walking home from work. I was contemplating the harmonic fractal nature of the universe at the major scales of matter, atomic-molecular-biological-organism-planetary-solar-galactic. Realizing this 7 part or octave structure was universal and that all agents are merely mechanisms of information transfer I suddenly awakened. My crown began to open and liquid electricity flooded my brain at the fountainhead. Suddenly I was in dialogue with my unconscious mind and we were in perfect harmony. This dialogue and exploration of my mind and body lasted for about 3 weeks. Over 20 days of intense self-realization. The world was vibrant and alive. I had conquered fear for a time, I could not feel fear no matter what. My tastes changed. My injuries healed. My body was in a state of excitation to the point my metabolism was consuming my body to renew itself. I had to urinate every 15 minutes, my energy was going up the spine, my sex drive was gone, the same energy that is felt in the genitals when aroused was leaving up into my crown, but my senses were beyond anything I had ever thought possible. My mind raced with new thoughts, and my imagination bordered on hallucinatory visualization. I could assimilate written text visually instead of using the mental verbalization I had been using to read before. I craved water and vegetation but lost my taste for sugar and meat. I was introduced to the new human being. Full of love and happiness and knowledge.
But then it stopped. I burnt out. I couldn't sustain it. The changes in my brain were permanent, but the energy to sustain it is not. I entered a deep depression that I'm still climbing out of. A process that may take 7 years according to some, this die off was punctuated with returns of the upflow and crown opening, but they were brief. Then a great bolt of energy shot up my spine at 3 am. I saw my body made of strands of blue and white light floating above me for half a second, before painful jolts flew up my spine and into my hands and head. Even now the activity returns when I type this out, my body remembers and tries to awaken when I think about it too much. I foolishly stopped the process and was burnt terribly by the friction. It has burned my mind and my spine and done untold damage to my nerves. The kundalini fire was burning but it was misdirected. It flailed wildly into my left and right hemispheres. Instead of a gentle river flowing in the center of my spine, it was a raging rapids burning my mind of impurities. This of course does as much damage as it does good. My mind is purer in many ways, but I am now highly unstable and lack a base, a grounding that would allow me to harness my energy properly. It isn't supposed to be forced, it is supposed to be allowed to open. This is why I meditate in a state of no-mind, as little thought and noise as possible. The body and spirit already know how to function properly, it is only we who stand in the way of our own self-realization.
But hope is not lost. I met a friend that had studied martial arts, including the subtle forms, and Neidan teachings of the subtle body. He recently told me my experience was of 'the spewing of the Mountain', the Chinese form of Kundalini. I've learned of the Microcosmic Orbit and the triple burner theory of the body. My stomach is of course where my surgery was, so there may be a leak in my enteric nervous system or the brain in my guts so to speak. But he told me the process is in order to destroy the old energy pathways and rebuild them. But that meditation is key to rebuilding the 10 centers or filters/purifiers of the body. Again, the intent of healing and purifying is all that is needed, meditating with a still mind and knowing, not forcing, but simply allowing what is natural to occur is the best way to do this. My practices are slow and infrequent right now, because I'm in college and would rather not have to risk blowout, so Im not pushing the issue.
I would suggest you too practice the construction of these purifiers. Each chakra, be it 7 or 10 or 12 or 13 or whatever you choose to visualize, is a vessel or watercooler of energy. The purpose of them is to route energy but more importantly to filter it into a pure state. Triple refined gold as the alchemists say. I experienced recently the throat chakra tingling and meditated upon it so it could teach me it's function and the place this tingling point of energy belonged. It moves left and right, mostly to the right, my dominant side, right at the back of my throat. When I centered it, it immediately shot straight down into my neck and to my belly where it sublimated into intense warmth, feeling like hot water, but also incredibly pleasurable. Suddenly my mental fog was gone. I had done it. Something is keeping my filters clogged on the return trip down the front of the spine, leading to this head pressure and psychosis, anxiety and inability to sleep properly. my lower back also has some form of block that tingles or sparks, I was told this is the constructor, the center that gives structure to the spinal energy flow. I have burnt the structure and broken my filters. My friend also told me because of my fearful halting of the process, it would resume where it left off, a violent and painful upward flow that destroys and creates all at once. However I read that focusing upon the heart center, the rhythmic resonator that organizes bodily function and generates the feeling of love without object, can bring about awakening safely and painlessly. This also seems to relate the phi ratio of natural systems, yin and yang, the phi spiral of DNA with 33 rungs per turn of DNA, the 33 spinal vertebrae. The heartbeat has an EKG spike that looks like the Fibonacci sequence converging on phi. It is our gateway to heaven. The heart from which the body emerges from our embryo really does contain the precept of God or the universal constants of life, or whatever else you'd like to call it, it is the truth, so there is no need to put it in a box with a name.
So I hope this experience is illuminating. Each of us has a subtle structure. This structure sometimes needs to be demolished in a sometimes painful way, if done improperly or by accident it can be downright deadly. So I suggest instead of forcing states of psychosis, work on the foundational levels of energy sensing, do not manipulate energies until you understand where they want to be in the body, and even then only guide them to your goals, never force, stay centered and grounded in all spiritual work, and continue to fortify and build filters for your system, to organize and purify the energy you want to work with. Meditate on void in order to understand detachment from ego mind that seeks to usurp power for selfish gain.
Then there is the physical aspect of the body that also needs attention. Research the limbic system and how it maps onto the body the chakras. The thalamus is the master gland of hormonal regulation, it is the base or root chakra. It gives a means of controlling emotional energies as well as healing and the hormonal state of the body that leads to either bliss or psychosis, or both, a deceptive cocktail of delusional grandeur. Sometimes this is necessary to mask the pain of awakening and purification. Sometimes it is a dangerous trap that ego claims itself God with. Emotional control is key to utilizing the body and mind. Conquest of fear and anger makes the right amygdala shrink until radical consciousness shift occurs and all experience is positive, shunted into the left amygdala, search "Mara's Demons and inter-hemispheric intrusion" for a fascinating article on Buddha's brain burning through his negative memories and manifesting them as hallucinations in the visual centers of the brain routing emotional energy between amygdala. But be warned that the path of the Buddha is dangerous, conquering the god of fear and death is not an easy or quick task, it is diligent mindfulness of our inner state and how it affects us and our actions. Watch our thoughts arise and resolve so they can not sway us with blinding passion. It still isn't clear if this state is truly good for us, but it does give humans a new outlook on life and the self. There lies a visual, non-verbal self that the non-verbal brain projects onto what we see, many confuse this with God, but it is in fact themselves, outside of themselves. It can become an angel, God, Jesus or even demons. Ultimately to transcend the self, we need to understand the other half of our self, the one that does not see itself, rather it is as one with the environment, instead of at war with it and the objects around us, including each other. We are all one.
Good luck with your journey and be safe!
