As an adult, Schwartz, still a bustling dynamo of enthusiasms, found an outlet in psychophysiology, then a fledgling study of the effect of the mind on the body. By the time he had accepted a post at the University of Arizona, which was known for encouraging freedom of research among its faculty, he had grown fascinated by biofeedback and the ways in which the mind could control blood pressure and a variety of illnesses – and the powerful physical effect of different types of thoughts.2
One weekend in 1994, at a conference on the relationship between love and energy, he sat in on a lecture by physicist Elmer Green, one of the pioneers of biofeedback. Green, like Schwartz, had grown interested in the energy being transmitted by the mind. To examine this more closely, he had decided to study remote healers and to determine whether they sent out more electrical energy than usual while in the process of healing.
Green reported in his lecture that he had built a room whose four walls and ceiling were entirely made of copper, and were attached to microvolt electroencephalogram (EEG) amplifiers – the kind used to measure the electrical activity in the brain. Ordinarily, an EEG amplifier is attached to a cap with imbedded electrodes, each of which records separate electrical discharges from different places in the brain. The cap is placed on a person’s head, and the electrical activity picked up is displayed on the amplifier. EEG amplifiers are extraordinarily sensitive, capable of picking up the most minute of effects – even one-millionth of a volt of electricity.
In remote healing, Green suspected that the signal produced was electrical and emanated from the healer’s hands. The copper wall acted like a giant antenna, magnifying the ability to detect the electricity from the healers and enabling Green to capture it from five directions.
He discovered that, whenever a healer sent healing, the EEG amplifier often recorded it as a huge surge of electrostatic charge, the same kind of the build up and discharge of electrons that occurs after you shuffle your feet along a new carpet and then touch a metal doorknob.3
In the early days of the copper wall experiment, Green had been faced with an enormous problem. Whenever a healer so much as wriggled a finger, patterns got recorded on an EEG amplifier. Green had had to work out a means of separating out the true effects of healing from this electrostatic noise. The only way to do so, as he saw it, was to have his healers remain perfectly still while they were sending out healing energy.
Schwartz listened to the talk with growing fascination. Green was discarding what might be the most interesting part of the data, he thought. One man’s noise was another man’s signal. Does movement, even the physiology of your breathing, create an electromagnetic signal big enough to be picked up on a copper wall? Could it be that human beings were not only receivers of signals but also transmitters?
It made perfect sense that we transmitted energy. A great deal of evidence had already proved that all living tissue has an electric charge. Placing this charge in three-dimensional space caused an electromagnetic field that travelled at the speed of light. The mechanisms for the transmission of energy were clear, but what was unclear was the degree to which we sent out electromagnetic fields just by simple movements and whether our energy was being picked up by other living things.
Schwartz was itching to test this out for himself. After the conference, he contacted Green for advice about how to build his own copper wall. He rushed to Home Depot, which did not stock copper shielding but did have aluminium shielding, which could also act as a rudimentary antenna. He purchased some two by fours, placed them on glass bricks so that they would be isolated from the ground, and used them to assemble a ‘wall’. After he had attached the wall to an EEG amplifier, he began playing around with the effects of his hand, waving it back and forth above the box. As he suspected, the amplifier tracked the movement. His hand movements were generating signals.4
Schwartz began demonstrating these effects in front of his students in his faculty office, making use of a bust of Einstein for dramatic effect. With these experiments, he made use of an EEG cap, with its dozens of electrodes. When not picking up brain signals, the cap will register only noise on the amplifier.
During his experiments, Schwartz placed the EEG cap on his Einstein bust, and turned on just a single electrode channel on the top of the cap. Then he moved his hand over Einstein’s head. As though the great man had suddenly experienced a moment of enlightenment, the amplifier suddenly came alive and produced evidence of an electromagnetic wave. But the signal, Schwartz explained to his students, was not a sudden brain wave emitted from the lifeless statue – only the tracking of the electromagnetic field produced by his arm’s movement. It seemed indisputable: his body must be sending out a signal with every single flutter of his hand.
Schwartz got more creative with his experiments. When he tried the same gesture from three feet away, the signal diminished. When he placed the bust in a Faraday cage, an enclosure of tightly knit copper mesh that screens out electromagnetic fields, all effect disappeared. This strange energy resulting from movement had all the hallmarks of electricity: it decreased with distance, and was blocked by an electromagnetic shield.
At one point, Schwartz asked one of the students to stand with his left hand over Einstein’s head, with his right arm extended towards Schwartz, who was sitting in a chair three feet away. Schwartz moved his arm up and down. To the amazement of the other students, Schwartz’s movement was picked up by the amplifier. The signal had passed through Schwartz’s body and travelled through the student. Schwartz was still generating the signal, but this time, the student had become the antenna, receiving the signal and transmitting it to the amplifier, which acted as another antenna.
Schwartz realized he had hit upon the most important point of all his research. Simple movement generated electrical charge, but, more important, it created a relationship. Every movement we make appears to be felt by the people around us. The implications were staggering. What if he were admonishing a student? What might be the physical effect on the student of wagging his finger while shouting ‘Don’t do that’? The student might feel as if he were getting shot with a wave of energy. Some people might even have more powerful positive or negative charges than others. In Elmer Green’s copper wall experiment, all sorts of equipment malfunctioned in the presence of Roslyn Bruyere, a famous healer.
Schwartz was onto something fundamental about the actual energy that human beings emit. Could the energy of thought have the same effect as the energy of movement outside the thinker’s own body? Did thoughts also create a relationship with the people around us? Every intention towards someone else might have its own physical counterpart, which would be registered by its recipient as a physical effect.
Like Schwartz, I suspected the energy generated by thoughts did not behave in the same way as the energy generated by movement. After all, the signal from movement decreased over distance, much like ordinary electricity. With healing, distance appeared to be irrelevant. The energy of intention, if indeed there were any, would have to be more fundamental than that of ordinary electromagnetism – and lie somewhere, perhaps, in the realm of quantum physics. How could I test the energetic effects of intention? Healers, who appeared to be sending more energy than normal through their healing, offered an obvious place to start.
Elmer Green demonstrated in his research that an enormous surge of electrostatic energy occurred during healing. When a person is simply standing still, his or her breathing and beating heart will produce electrostatic energy of 10–15 millivolts on the EEG amplifiers; during activities requiring focused attention, such as meditation, the energy will surge up to 3 volts. During healing, however, Green’s healers produced voltage surges up to 190 volts; one produced 15 such pulses, which were 100,000 times higher than normal, with smaller pulses of 1–5 volts appearing on each of the four copper walls. On investigating the source of this energy, Green discovered that the pulses were coming from the healer’s abdomen, called dan tien and considered the central
