Grabovoi codes are specific number sequences — typically 6 to 10 digits — that are said to resonate with particular states of health, wellbeing or abundance. Each code corresponds to a specific intention: there are codes for attracting money, for healing specific organs, for finding a romantic partner, for improving eyesight, for passing exams. The codes are used by focusing attention on the number sequence while holding the desired outcome in mind.
The codes derive from the work of Grigori Grabovoi, a Russian mathematician and self-described psychic who developed what he called the "Grabovoi Method" — a system based on the idea that reality is fundamentally numerical and that specific number sequences can interact with the body's and environment's informational field to produce desired changes. Grabovoi presented his system in a series of dense, mathematically inflected books published primarily in the early 2000s.
The theoretical framework draws on several streams: Soviet-era parapsychology research (which was state-funded and serious during the Cold War), radionic theory (the idea that biological systems have characteristic frequencies that can be influenced by resonant signals), and elements of sacred geometry and number mysticism. Grabovoi claimed to have developed the codes through a combination of mathematical calculation and direct clairvoyant perception of the informational structure of the universe.
