The subtle energy systems in the body
The body functions through various systems like the cirulatory system, respiratory system, digestive system etc. Similarly there is a system to provide energy to the physical as well as subtle body. The components of the subtle body are denoted by the star against it in the diagram below.

The other systems can be seen by dissection of the physical body. But the subtle energy systems are not visible to the gross eye. Only those people with an active sixth sense can perceive it. Some people equate this subtle energy system with the nervous system but this is incorrect.

Just as the heart is the principle centre (organ) of the circulatory system and the brain of the nervous system, similarly the subtle energy system has various centres. They are known as ducts (granthi) and centres (chakras). All the ducts and centres are situated in the Central Channel (Sushumna nadi). In the subsequent articles we discuss these subtle energy systems in detail.
