There are only two things in this world capable of repairing the horrific diversity of the human world:
The divine breath within us and the light of the Torah that guides us.
So, there's a very simple test to find out if the Torah you study and the Mitzvot you fulfill are truly occupying your soul:
Are you creating more harmony in your world? Are people getting closer?
As Rabbi Janina Ben Dosa used to say: "If people enjoy having you around, God also enjoys you.""
