Mother Stands for Comfort Lyrics

Lyric discussion by Asterion 

Cover art for Mother Stands for Comfort lyrics by Kate Bush

I always thought it was poignant how "Mother Stands for Comfort", and the following song "Cloudbusting", are thematically very similar. Both songs deal with the way people, particularly family, defend each other against the persecution of society. There is an element of blindness when it comes to protecting a person we love. Kate is conflicted in this song about the balance that is upset by a destructive force, and the instinct to hide what is destructive in ourselves and in the ones we love. How do we come to terms with the duality and moral ambiguity within ourselves, much less the world at large?
