Avodas Hashem IS being in touch with your neshoma, because you’re feeding it what it needs, i.e. Torah and mitzvos, which the tanya calls “food” for the neshoma (regarding learning)
I’ve seen it quoted in the name of the baal shem tov that one shouldn’t dwell on their level, because if you’ll think you’re a tzadik, it’s gaavah, and if you think you’re a rasha, it’ll lead to depression, so just constantly try to do your best.
