I also am interested if these seizures are a medical problem, or an intensive process you’re passing through on your path of spiritual growth. In particular, I am reminded of Krishnamurti. I don’t want to be dangerous in disregarding something that might be symptomatic of a deeper issue. Still, I do think it’s important to understand another perspective on psychological growth phenomena, no matter how irregular. (I have been through some similar phases of intense mental/physical agitation giving way to tremendous peace. I think they can be valuable, but it really would be very advisable to have some support form your community…)
here is an excerpt from the WIkipedia entry detainling Krishnamurti’s episodes, which struck intermittently for about a year, and have become a defining moment in his biography:
"…It was there, in August 1922, that Krishnamurti went through an intense, “life-changing” experience. It has been simultaneously, and invariably, characterised as a spiritual awakening, a psychological transformation, and a physical “conditioning”. Krishnamurti and those around him would refer to it as “the process”, and it continued, at very frequent intervals and varying forms of intensity, until his death. Witnesses recount that it started on the 17th, with extraordinary pain at the nape of Krishnamurti’s neck, and a hard, ball-like swelling. The next couple of days, the symptoms worsened, with increasing pain, extreme physical discomfort and sensitivity, total loss of appetite and occasional delirious ramblings. Then, he seemed to lapse into unconsciousness; actually, he recounted that he was very much aware of his surroundings and while in that state, he had an experience of “mystical union”. The following day the symptoms, and the experience, intensified, climaxing with a sense of “immense peace”.[43]
"...I was supremely happy, for I had seen. Nothing could ever be the same. I have drunk at the clear and pure waters and my thirst was appeased. ...I have seen the Light. I have touched compassion which heals all sorrow and suffering; it is not for myself, but for the world. ...Love in all its glory has intoxicated my heart; my heart can never be closed. I have drunk at the fountain of Joy and eternal Beauty. I am God-intoxicated."
Let’s not get too googly eyed ourselves, I don’t want to hurt anybody and send them off an a delirious mystical quest, but honestly, I have become more wary of needless medical intervention that stunts the process of spiritual growth than the experience of perplexing phenomena that might seem frightening to the outside world, but are silently accepted and understood by the inner self.
I can’t stress enough how important a physical teacher has been to me. I wish you would not be so meek in your practice, and find a way to bridge a gap between two beautiful spiritual traditions (each of which have their own corruptions). Maybe just speaking with people, calling it “exercise” or “stretching” and explaining what it has done for you will get them over their fear of “other”. I understand, as I too have been in Christian communities (well, we’re speaking of certain types of Christian communities, not the larger spiritual tradition) as a yoga practitioner, and chose to minimize its outward exposure.
God bless you, and good luck.
I feel the most important thing is peace with your own Self. If you are doubting and worried about what might be happening, seek any attention you can get. If you feel greta about it, and even, as you say, look forward to it, rest in your own sovereignty over your own life experiences. I really hope I am not sounding ignorant and caustic, but the process of spiritual growth is almost universally understood, in my experience, by western medicine, and in some cases, stunted by it. Good luck, god bless you, may you make your home in that peace.
