Yes, if you take the illustration of the "narrow road" that leads to "life" (finding the self) you could apply it to the struggle for and maintainence of truth and honesty (integrity)in ones life and the relatively "few" that choose that path.
First one needs to recognise the lies and then have the courage to reject them and walk away choosing this puts you in a precarious place socially and emotionally being at odds with most if not all the people you knew and loved and who you thought loved you. So in a sense a "narrow road."
It would seem at times it would have been much easier in many ways to just keep going along with the lies to get along and appease others like a "broad road" that leads to the "death" of self and the majority choose this.
As you can see I have given it some thought, lol, kind of "hero of a thousand journeys" type stuff.
