How does Douglas Coupland use imagery in Generation X: Tales for an Accelerated Culture?

In Part III, Couplanduses the "light" motif or imagery, to illustrate the affirming blaze of illumination that erupts into the lives of Andy and his family. It's important to note that in this case, "illumination" refers to both the physical illumination of the candles and, in Andy's case, the psycho-spiritualemotional illumination that it's coming time for him to transform into a truer, more selfaffirming human being.
