The Chakra is a Spiritual energy centre, which lies just within the energy field of the body, connecting into the physical body. They are shaped like a cone, which spins as a vortex of energy literally taking the Universal power into the body, where the hormone glands alter it to our vibration. The main chakra colours radiate into the auric field, colouring our energy field.
Luminous fibres create the effect of a web around the body. It is this glow, which is seen around the physical body.
What you are seeing is the connection of physical with the Etheric. There are nadis over the liver and stomach areas and nadis in the palm of the hand and soles of the feet. These are what we feel ‘activate’ when sensing energy or carrying out healing.
We may be totally unaware of our chakra system, but generally speaking we actually 'feel' it daily. It can be a tightening of our abdomen, an increase in our heart rate, a lump in our throat, a sense of excitement - it can be a good feeling or a feeling of anxiety.
When people attend a yoga class of practice meditation, tai chi etc, they naturally are balancing their chakra system. Imagine your car tyres and you have let out most of the air from one tyre. You drive along, feeling the bumps in the road, aware the car is unbalanced and out of alignment. It makes the car seem unstable, the other tyres do not perform as well as they do when all are at the right pressure. We are just the same. We need balance to feel ok.
Having a treatment helps 'balance' this energy and keeps us feeling more aligned and relaxed.
