We've all heard about an illness in central Africa called sleeping sickness. What we should also know is that a similar disease exists that attacks the soul. It's very dangerous because the early stages often go unnoticed. At the first sign of indifference or lack of enthusiasm, take note! That only preventive against this disease is the realization that the soul suffers, suffers greatly, when we force it to live superficially. The soul loves all things beautiful and deep.
