Likkutei Torah notes (Shir HaShirim 38d) that just as there is a mitzva to “be fruitful and multiply” in the physical realm, there is a similar mitzva in the spiritual realm:
One must reach at least one new Torah insight each day.
This is true in the wider sense of this obligation as well. For even if the new insight is not always a spectacular innovation, and sometimes it may not even make sense, the main thing is not to suffice oneself with the world of stam.
Instead, one must fight the world’s existing format and flux by raising questions.
–Rabbi Adin Steinsaltz
