REASON FOR THE CHANUKAH DREIDEL
dreidel spinner is grasped from its top and set to spin.
This is symbolic of the heavenly inspiration that brought
about the courage and bravery of Yochanan, Mattisyahu and
his sons the Macabees to wage war against the Hellenists
that tried to destroy the Jewish nation during the times of
Chanukah. Whereas the miracle of Purim came about through
the fasting and praying of the Jewish people under the
leadership of Mordechai and Queen Esther, an inspiration
from below. So we use a grager on Purim to drown out the
name of Haman every time it is mentioned during the reading
of the Megillah, which is grasped from (the handle) below.
