Sometimes there might be bursts of energy, called Kriyas, which cause a jolt throughout the spine (meru danda) and the body. They may be sharp, quick, and mild, or they may come as a powerful jolt that causes the body to jump. Such a jolt may come from time to time in meditation, experienced as a single burst of energy. These often bring varying degrees of fear, as they may seem to be a threat to our existence. Gradually, as the energy is understood and assimilated, the Kriyas come more like a quick wave of reassuring warmth, which brings a wave of peace. They serve as gentle reminders of progress on the spiritual journey.
Kriyas are neither seizures nor Kundalini: When not understood, these Kriyas can be confused with seizures because of the way they cause a jolt in the nervous and muscular systems. Because of the warmth or peaceful feeling that can come with, or after the Kriyas, they can be confused with Kundalini Awakening, which they are not. Once again, they may be pleasant experiences that serve as inspiration along the journey.
