THE SEVEN CHAKRAS
In the human body are three main channel or nadis as they are called in Sanskrit called Ida, Pingala and Shushamna which are called in English as the sympathetic parasympathetic nervous system, these three nadis are situated along the spinal cord and they run in a curved manner which can be likened to a snake, these three nadis in this curved movement overlap each other and at the various fields of crossing an energy field is created which flows in an circular manner which can be compared to a wheel or a chakra hence the word chakra is used to describe these centers of energy, the frequency of these energy fields increases from the lower to the higher chakra i.e. the force which is generated increases from the lower to the higher.
