Nadis are energy pathways throughout the body—were detailed thousands of years ago as part of traditional Indian medicine. Nadis transport prana, the energy equivalent of chi. These channels emanate from the chakras and gradually become thinner the further they extend outward. This configuration is similar to the nervous system in that the chakras correlate to the central nervous system and the nadi pathways correspond to the peripheral nervous system. Although comparable to meridians, nadi pathways are more numerous as there are thought to be over 72,000 points of stimulation along these routes compared with the 361.
