““Most human disease and degeneration are caused by adverse external and internal energies created by noxious environmental conditions and extreme emotions, which lower resistance and impair immunity. By taking measures to counteract adverse environmental energies and control injurious emotions, and by cultivating pure energy, you can maintain a strong defence of resistance and immunity in order to prevent the Six Evils and Seven Emotions from disrupting your essence and energy and paving the way for invasion by germs, toxins, parasites, and other pathogens.””
