“Education is a light in the dark”

To me this quote means education is a light to brighten the empty dark.When your mind is a new mind it is filled with dark, every memory is a light used to illuminate the dark,some lights are brighter than others and take up more space, small lights die out over time as memories are forgotten,even some of the big lights die out as time takes its toll,and then again your mind is black as age overcomes you.
