Cover art for Janitor of Lunacy lyrics by Nico

I think the verses that start with "Janitor of lunacy" tells the story about how religion has been embedded in a person since birth by society. It portrays how there is a lack of choice in what to believe, how to go in life, who to be- that everything should be according to the religion.

With the line starting with "Janitor of tyranny" then states how vain or sinful actions could become blameless since the society itself is dictating what things are corrupt and not.
