The energy system of our bodies is much more complex than you might imagine. In addition to the seven layers within each person’s aura, there are also seven chakras, or major energy centres, which run in a vertical line through the centre of the body, from the bottom of your trunk up to the crown of the head. This can be a difficult concept to grasp at first, especially as the chakras do not manifest physically. However, they do exist at an energetic level, where they enable the body to regulate itself and operate efficiently. There are also 21 minor chakras, which are found mostly on the trunk, but also in the hands, head, knees and feet. There are several higher chakras as well with more to be discovered.
Chakra is the Sanskrit word for wheel, because the chakras are seen clairvoyantly as spinning wheels of energy. When a chakra spins perfectly with no obstruction, distortion or sluggishness, it is functioning well and will not cause any physical, emotional or mental problems. However, these problems will start to manifest if the chakra stops running smoothly for some reason. You could think of it as a battery running down there : everything controlled by that battery will also start to slow down.
 
WHAT ARE CHAKRAS?
The aura consists a network of fine lines, each of which is called a nadi. Chakras are the junctions where many of these lines of energy meet. The major chakras occur at the seven points where the greatest number of lines converge. Each major chakra is associated with specific parts of the body, with a time of physical development and with a colour. Minor Chakras occur at the 21 points where a smaller number of lines meet. These chakras have been found to coincide with areas in the body that are rich in nerve endings.

Each chakra regulates a specific area of the body, as well as the emotions, mental outlook and spiritual purpose connected with that part of the body. For instance, is someone describes themselves as ‘ broken-hearted ‘ over a love affair, it is their heart chakra that needs attention.  Chakra’s also enable us to use our psychic gifts and to connect with one another on a psychic level. For instance, healers use their heart, hand and solar plexus chakras when giving treatment.
