Theme when you are writing a paper you want it to talk about life but not tell the reader how to live just give them ideas and let them comprehend it 

The right answer is "Theme"

In this way the complete sentence would be:

"Theme is a comment of life, not advice on how to live".

Theme, as a comment of life is when one is debating on important points that have happened in the life of an individual without advising, giving personal opinion, on how it should act, only discussing about this important point.
