"Ki" is life energy. It is also known as the vital life force or universal life energy. This is the non-physical energy that animates all living things. As long as something is alive, it has life energy circulating through it and surrounding it; when it dies, the life energy departs. We are more than our physical bodies. We also have an energy body made up of our aura (energy fields), the chakras (energy centers) and the meridians (energy pathways). Like our physical body that takes in food to nourish it and give it energy, our energy body does the same. The energy field takes energy in, the chakras break it down, and the meridians distribute it throughout the body.
