The body’s energy field has been studied for thousands of years. Many traditions use the chakra system, and so does Shamanism. Reiki healers, chiropractors, massage therapists, and acupuncturists use the energy fields in the body to heal. There is an abundance of resources and information on the internet and in books on chakras. I encourage you to explore for a deeper understanding.
My basic explanation follows the illustration, starting at the bottom and working up.
The Second Chakra is located in the abdomen. This is the center for emotion, sexual energy, and creativity.
The Fourth Chakra is the heart chakra. Love, balance and compassion reside here.
The Sixth Chakra, often called the Third Eye, is located in the middle of the forehead. Here Intuition, psychic abilities, and imagination reside.
