In the early 1900s, British physician Walter Kilner conducted groundbreaking experiments using Dicyanin dye filters, claiming they revealed the human energy field, or “aura.” By looking through specially treated glass, he observed subtle energy patterns surrounding the body, with colors and intensities that seemed to reflect a person’s health and emotional state. His research captivated occultists, spiritualists, and early parapsychologists, who saw it as scientific validation of unseen forces. Though controversial, Kilner’s work laid the foundation for modern aura photography and continues to influence alternative medicine theories on bioenergy, chakras, and human energy perception.
