As the other comment pointed out, it simply means to see that everyting is in unity, everything is part of the same universe, same god. To not get only one part of the world (like fame or material possessions, or a single other person, or affiliation with a political party) and make it your idol god, because that will ultimately lead to disaster. There is nothing "jealous" about this.
