Have seen contradictory information regarding the reward for someone who brings merit to the public.
On one hand, I've heard Rabbis say that one who causes another to learn torah also gets the reward for that person's torah study. (they base this on chovos halevavos in gate#10)
On the other hand I heard a shiur by Rabbi Nissan Kaplan who says that if one learns one hour of torah, it is greater merit than opening up a yeshiva where hundreds will learn torah. He bases this on a Taz who says that Mordechai would have had more merit if he had stayed and learned instead of saving all of the jewish people. (the talmud also says that torah study is great than hatzala nefashos)
can anyone resolve this?
does causing someone to learn torah really have the same reward as learning oneself?
