What is the Polarity... Polarity refers to the electrical nature of the universe, but more specifically the body and brain via the nervous system.
In an electrical entity you have the 3 main dynamics of positive, negative and ground... further broken down into sensory, functional and automatics via a conductive network. This does not only include the nerves, however the main response or reactions are transduced (to convert (as energy or a message) into another form) through them. Going further; there is also a field of energy emitted through and around us, electrical in nature and detectable on scientific equipment... called the magnetic field exactly like our own planet.
Electrical polarity (positive and negative) is present in every electrical circuit. Electrons flow from the negative pole to the positive pole. In a direct current (DC) circuit, one pole is always negative, the other pole is always positive and the electrons flow in one direction only. In an alternating current (AC) circuit the two poles alternate between negative and positive and the direction of the electron flow reverses.
In AC systems the two wires alternate polarity many times per second. In this context, "polarity" refers to the order in which the neutral and phase wires are connected. This is meaningful only with respect to ground potential. Reverse polarity could be dangerous.
This is similar as well in the human body and can be used to our advantage in combative need. It is also perfect blend of science, medical, anatomical, physiological and martial disciplines as they are embodied in a single understanding. We can learn to weaken the opponent by using this understanding of their electrical system as it alternates from positive (motor nerve transmission) to negative (sensory nerve transmission) as well the polarity or flow to and from each state.
This information is complex, but more easily explained in Martial Art methods... as the trained actions teach you how to transfer polarities as well as grounding and ungrounding these potentials, so all you need to do is perform a physical action without the thought process.
Many of these polarity switches are fully functional to get past the Iron Shirt methods of many styles and was the precursor to the Iron Shirt film which got into greater detail. The methods are only shown in step by step separated format to further illustrate how this form can enact the polarity change methods on another individual.
There are over 30 methods for you to experiment with as you learn about the human electric field. The core principle in this presentation is attacking the electrical systems of the body and or using their properties, function and polarity or cause further disruption in the body.
More specifically to manipulate the energies or nervous system to disable natural protections of the body and leave the opponent more vulnerable to attack.
