Dear Marcy:
I have been practicing Spring Forest Qigong for only a short time and have also experienced chilling sensations during and after performing the Active Exercises.
I am a chiropractor, who utilizes a method, which helps facilitate release of meningeal tensions held within the nervous system’s spinal cord. During care, as our patients progress through spinal release toward meningeal ease, frequently, they almost predictably mention very similar cold sensations that may be described as ‘deep bony chills’ – for this time we have blankets to offer for added comfort. We practitioners have been informed that the chilling sensations are indicative of release of mechanical cord tension from within the nervous system (Phase 5, of the adjusting protocol).
I am unsure, whether or not what you describe is Qigong’s similar releasing effects on our central nervous systems, or whether, as hypothesized, the effect is an indication of kidney system challenge. Personally, chills indicate shift is taking place; leading to further healing potentials.
Many of my own adjustments/entrainments have resulted in remarkable MindBody response – many of which have been heavily cathartic. I have spent many years attempting to realize that which is happening is not to be judged as ‘bad’, but rather it is the body’s response through its perfect healing processes.
I hope that I am able to offer another insight into the perfection of your own Innate Intelligence.
Love and Peace,
Joe
