See for yourself- Watch the energy pulsing at my throat.
Just like the Universe, our bodies are full of energy. Energy can be hard to define, even for top notch scientists like Einstein but nonetheless everything in this Universe is made of atoms, most with electrically charged particles so we are full of it. How healthy we are and how much energy building activities we do like Yoga, Acupuncture, Meditation or Tai Chi determines how strong and how much control over our energy we have. There are many different types of energy from potential to chemical to thermal, which we also have but our body’s energy flows mainly as Bio-electromagnetic energy through currents or pathways throughout the body. We have both electric and magnetic fields.
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.
