Experiencing Muscle Spasms/Quaking in Chest
Hi all, I'm posting in hopes of clarification. I have been an on and off meditator for 10 years now, but have never practiced Kriya or Kundalini yoga. Almost a year ago I was sitting quietly in a park, I had finished my meditation, (I just listened to Alan Watts' guided meditation on youtube) and I started to feel a sensation, almost like convulsions or muscle spasms similar to shivering after cold water exposure, in my stomach and chest. I noted the novelty of the experience, but didn't really pursue it much. At random times since then I'll feel a little twinge, and occasionally a more intense stomach spasm, but the sensation doesnt really grow much unless I focus on it. Recently I tried to explore the sensation more, and did really slow, controlled inhalations and exhalations.The vibrations seemed to continue up into my throat and behind my mouth, but I have no clue what I'm actually doing, and have reservations about continuing to try and grow the sensation higher up into the third eye and crown chakras areas for fear it may be some kind of kundalini something or other? Either way, I was able to find peace and calm my nervous system down during a time of much uncertainty and self deprecation, and felt like I was coming close to accessing the present moment, almost like I forgot my name and who I was for brief moments. I'm just wondering if there's teachers or books that I could contact or read to find out what's going on in my body and how I can make use of it to mediate my suffering and find more peace in my life. Any information would be so greatly appreciated. Thank you
