"Be like night" vs "Be like the night"

I'm sorry if this question is somewhat basic. I have a sentence here that goes like this:

Be like night, in covering others’ mistakes
And like the earth, in being humble;
In love and friendliness, be like the sun;
And during anger and rage, like a mountain;
Be like a river in generosity and helping others;
And in coping with others, like a sea.

But the "like night" part, sounds somewhat off to me. should I use the here as well, or this is OK as is?

By dropping the article, the author is personifying 'night'. None of the other allegories used lend themselves to this.
