In "The Law of Vibration," Tony Plummer presents a new theory that reveals a fundamental truth about the deeper structure of the universe. The law is embodied in a specific oscillation pattern that accompanies change and evolution. This pattern can be found in the fluctuations of stock markets and economic activity. Research suggests that this pattern was already known in ancient times, as it is hidden in a brief passage in the Gospel of Matthew in the Bible. It also indicates that it was recognized at the beginning of the 20th century, concealed in the works of the renowned stock trader William D. Gann and the mindfulness advocate George Gurdjieff. Both men chose to preserve their knowledge of the pattern in a hidden form for an unknown future purpose. After 20 years of investigation, Tony Plummer recounts the story of how the pattern was originally concealed. Based on meticulous research in gematria, the Enneagram, and financial market analysis, Plummer reveals a behavioral pattern that could have profound implications for our worldview. His work is elegantly structured and thoroughly illustrated, making it an exciting and thought-provoking study for Gann enthusiasts as well as for investors, economists, and scientists interested in the laws that underpin systemic coherence and generate collective order.
