in one sense, in which this could be complicated because dark and light work for each other, you are the proverbial light worker when you are aware of at least some forms of darkness in which i mainly find myself shedding light on people's innocent ignorance, you could be sacrificing your "image" to stand up for something you believe in that will bring good to the world that many people don't understand, diffusing anger driven situations, all types of healing, i do find myself tending to people's naivety more though to help them become more aware, i guess helping people become more aware of themselves and of life, their surroundings, but also letting them find there own way of course, and many many other things some more direct, some you gotta be as clever as what caused the shadow, the eyes wide shut. you could also be a light worker and not be aware of it, that is extremely beautiful, just doing it from within.
