Fritz-Albert Popp (1938-2018) was a German biophysicist and cancer radiotherapist. He is the father of Biophoton Theory, which postulates DNA as the source of biophoton emissions. Popp also coined the term "biophoton", and founded the International Institute of Biophysics in Neuss, Germany. His extensive research led him to the conclusion that humans are, essentially, beings of light.
Prior to Popp, a couple of other prominent scientists also came to the same conclusion:
When a person is in a neutral state of mind, their biofield radiates 4-6 ft. beyond their body. However, the biofield expands and contracts as the result of one's positive or negative thoughts and emotions, the state of one's health, and various other endogenous and exogenous stimuli. The portion of the biofield that is closest to the body is known as the aura, and can be seen with minimal effort. This field of light can also be photographed, using specially equipped aura cameras.
Auras have different colors at different times. The colors in a person's aura are an indication of the dominant frequencies in their biofield, which are determined by that person's thoughts, emotions, and overall health and well-being at that particular moment. Higher frequencies in the aura are the result of a higher vibrational state of consciousness, whereas lower frequencies indicate a lower vibrational state of consciousness. The state of consciousness is not due to intelligence, but is rather an indication of a person's overall conscious awareness.
A person's vibrational frequency determines the color of their aura at any particular moment. The frequency and colors change according to their thoughts, emotions, and overall state of health and well-being. The colors are also an indication of which subtle energy centers, or chakras, are most predominant at the moment. Reds and oranges are indicative of the lower chakras, yellows and greens correspond with the middle chakras, and blues and purples are tied to the upper chakras. The chakras are explained in detail on the Caduceus page.
In 1939, Russian electrical engineer Semyon Kirlian and his wife, Valentina, developed Kirlian photography, which was used to capture electrical coronal discharges around living and non-living things. Since that time, many improvements have been made in the process, and there are now cameras and video equipment that can photograph the human aura and video it in real-time. At HeartMind Institute, we use aura photography and videography in our classes and workshops to show participants how their energy field changes with their thoughts.
HeartMind Institute uses aura photography and videography during our workshops to demonstrate how thoughts and emotions affect the vibrational frequency of the biofield. We take an aura photograph and/or video when a participant first arrives, and then again at the end of the workshop, after they have had biofeedback practice, brainwave synchronization, heart rate variability training and meditation sessions. We then compare the before and after photos/videos to see how their aura has changed over the course of the workshop.
