Without Pressure and Suction terminals there could be no currents. For instance, water could not pass through a hose without Pressure and Suction. Pressure forces water through the hose, and the air at the end of the hose, which is of lesser density than water, is the Suction terminal that draws the water to it. If there were no opening into the air there would be no Suction terminal and no matter how much Pressure there might be exerted there could be no current. When water is forced upward through a hose the Suction point is the air at the end of the hose, but as soon as the water passes out of the hose the Suction point then becomes the center of the Earth toward which it falls, because the lesether within the Earth is of lesser density than the air or ether surrounding the Earth.
Suction draws against Suction and Pressure pushes against Pressure.
A man standing upon his head can drink water that will be drawn upward through his throat and esophagus to the stomach by the internal Suction of his body although his body is drawn downward toward the center of the Earth. That proves that the internal Suction of a body contains more force in so far as it relates to its internal machinery than does the formation to which it is drawn. Man is drawn to the Earth by the Earth's Suction but still the blood in man's feet is drawn upward by the Suction of his heart. Concentrated Suction within a formation therefore must be greater for its internal workings than the greater Suction of the formation to which it is attached. If this were not the rule there could be no formations and therefore there could be no movement or balance of matter.
