Many Names, One Energy
Now, this energy and these currents have been called many different things in different cultures but whatever you call it, they are all describing the same energy. In Chinese Medicine it is called chi and it travels through meridians. In Ayurvedic Medicine and Yoga terminology- it is called shakti or kundalini and it travels through nadis and chakras. Now in western or modern day western terms, it would be described as bio-electromagnetic energy that runs through our bodies in different circuits.
