I do not know about this particular system of yoga but whenever pranayama and shambhavi are put together, without mantras and without proper initiation, it is quite likely that some percentage of people will have prana energy problems such as these. Oh yes, my analysis based on many similar cases is that this is a pranic disharmony (note: There is actually no such thing as “kundalini syndrome”, it is all prana problems). It can only be fixed with proper mindfulness/meditation paractice in a tutelage of a competent teacher or by receiving energetic help from a specialist healer or receiving energteic help from a valid spiritual (tantra-mantra) teacher/master.
What do you mean by the vibration in legs? Describe it in more detail, please.
Thanks @Babananda for your thought on this. Yes i came to know about the prana energy problem from some source at internet when i was searching after this problem but now i don’t remember that source. As you said it can be fixed with proper mindfulness/meditation practice. Can you please guide me on this? Can you please suggest me some meditation practice and energy healing technique or source? Currently i don’t have access to any competent teacher or specialist healer.
My mean by Vibration in legs is that after some days of injury in back i started to feel random nerve moment in my legs. My whole legs doesn’t shack but i can feel small portion of my legs have random nerve movement right under my skin. I feel that movement of nerve if i look at that portion of movement i can see something vibrating under the skin. This sensation last for 2-3 seconds. These kind of movements are very random and i can feel those in several part of my body like back, shoulder and hands. This could be Dyskinesia or any other Movement disorder.
