L'Chvod Rabbi Shapiro, Shlita:
I wasn't certain as to where to post this topic, so please have it moved if it's not in the correct Forum.
1) Why are:
a ) the place where Hashem put Adam and Chava in this world to live, and
b ) the place in the Next World where Tzadikim go after death for their reward,
both called Gan Eden?
2) Where in this world is the location of the Gan Eden where Adam and Chava were placed to live, before their sin?
