The document discusses the concept of suppression in homeopathy and how it can occur when the correct simillimum is not found or the cardinal principles are not followed strictly. Suppression occurs when the disease is weakened in one area but ends up strengthening in another, more important system. This happens through the 7 layers of suppression which track the progression of disease from skin to nervous system based on embryological development. Identifying and understanding the layers of suppression is important for homeopaths to avoid suppressive treatments and ensure cure by following Hering's law of cure.
