The Middle Column
DescriptionThe Middle column of the Sefirot structure represents the ideal balance of divine mercy and justice. This harmony is best represented in the Sefirah of Tiferet, which exists midway between the extremes of Din and Hesed, female and male.
Following traditional Rabbinic perception, the Kabbalah recognizes that the universe could not survive if it were founded only upon justice or only upon mercy.
