There's a popular song sung in shuls on Simchas Torah during Hakafos. The first two lines of the song are:
Olam Habah is a gutta zach
Learning Torah is a besser zach...
(Translation: The World to Come is a good thing, learning Torah is a better thing...)
This song has always struck me as kind of odd. Olam Habah is supposed to represent the ultimate reward that we receive for following God's will. It's the light at the end of the tunnel, the pot of gold at the end of the rainbow, etc.
And yet, the song seems to state that learning Torah is a better thing. Does this mean that when Talmedi Chachamim die it is a punishment for them since they can no longer learn Torah here on Earth and going to Olam Habah is a "lesser" good?
