Albert Schweitzer likened a disease in central Africa called 'sleeping sickness'" -- what we call narcolepsy - to a sleeping sickness of the soul. Its most dangerous aspect is that it sneaks up on you. Schweitzer wrote: "As soon as you notice the slightest sign of of the loss of a certain aliveness, of longing, of enthusiasm, of zest, of zeal, take it as a warning. You should realize your soul withers and suffers if you live superficially." By contrast, zest and enthusiasm is our soul's signal to us that we're in touch. So ask yourself, "How alive do I feel? Am I full of enthusiasm or have I lost my zest for living?" We all have the capacity to awaken from slumber to greater aliveness.
