Question

I would be happy to hear your opinion about the place of emotion in Judaism. Is there some added value in serving God with emotion, in observing commandments with emotion, in having a personal and emotional relationship with God, love, awe, and the like, or is it all imagination and gut nonsense, and one should observe the commandments dryly exactly as written, with no point in adding anything beyond that?
Sometimes I see a Jew who literally lives every moment with God: he prays with emotion, observes commandments with devotion, and is deeply moved. I’m very impressed by that, but I want to know where all this fits within Judaism.
