1-40b-קידושין-מ-ב- תלמוד גדול שמביא לידי מעשה

Is the whole purpose of limud hatorah is in order to know the halacha ("תלמוד גדול שמביא לידי מעשה"). Do you get up bemesirus nefesh at 5:30am every day to find some nuggets of halacha lmaaseh in maseches erchin and kiddushin? Do you not leave the page until you check out the Shulchan aruch? “Mevatlin talmud torah le’mikrah megillah”. Why is listening to the megillah not considered limud hatorah? Enjoy!!
