That fisrt line is very foggy in its meaning. Your ghost gave you life, the light gave you life, the traveler gave you life. The closest thing to the opposite of a ghost to me is an ahamkara from what i understand because ghosts guide and the ahamkara lead you off the path and corrupt. The oppostite of light is the darkness duh. Im not sure what is considered the opposite of the traveler. My best guess is thorn or an ahamkara.
