If you have epilepsy, we recommend you do not use the visualizations as they can affect people with epilepsy. Many people though have been successful without the visualization just by reading the book alone. We also have visualizations without music (which is what can cause an issue). Please email help@thegabrielmethod.com for more information about these visualizations. Disclaimer: The Gabriel Method is not intended to treat, cure, or prevent any disease or illness.
