Prana is a Sanskrit word that means 'Life Force.' This invisible bio-energy or vital energy keeps the body alive and maintains a state of good health. Every culture speaks about this life energy in their own way. In acupuncture this energy is called Chi. Pranic Healing utilizes this natural life force to accelerate change to the physical, emotional, mental, and subtle bodies therefore bringing the experience of healing.
Pranic Healing is entirely done without any physical touching. It is applied on the bio-electromagnetic field know as the aura, or energy body, which is a mold or blueprint that surrounds and interpenetrates the physical body. This bioplasmic body absorbs life energy and distributes it to the organs and glands. Diseases first appear as energetic disruptions in the energy field before manifesting as ailments in the physical body. In short, the physical realm is the least subtle of all realms and is the last place any energy manifests.
Pranic Healing is primarily cleaning and sweeping out stagnant energy, when done, the bodies (emotional, mental, physical, subtle and astral) naturally realign themselves with the fresh and vibrant pranic energy put in. It is peaceful, restorative, balancing.....and it feels gooood!
