Kundalini is life force energy. Also known as prana or chi, Kundalini is a Sanscrit word that identifies the rising of an energy that is coiled at the base of the spine. It is believed that we carry this energy with us from the time we are born until it is released at the time of passing.
We are electrical beings, so imagine your chakras as running on an electrical board or circuit system of some kind. As Kundalini energy rises and travels up your spine, the energy passes through each chakra, giving them an energy boost and causing them to ignite or light up. When this type of energy rise happens, deep healing begins to take place on all levels.
