Why might someones body jerk, as the Kundalini rises?
If we believe that a jerking body is a sign of our kundalini raising, then our belief will cause our body to jerk. Yogi Bhajan calls it Jerk-Yoga. Excessive toxins throughout our body can obstruct the flow of energy and cause a vibration in the corresponding space. It may be felt as a slight trembling. It will soon pass as the toxins are eliminated. A weak nervous system can also cause vertigo (dizziness and confusion). That’s why in Kundalini Yoga, we do kriyas (exercises/meditations) to build up our nerve strength first. Generally we start a kriya with a time of 3 minutes, then add one minute a day, to slowly detox and increase our stamina.
