As I am not a Kabbalist I may be misunderstanding some of the terminologies but having recently read a work by Rav Kook zt"l regarding the Souls of the World of Chaos I noted that the overall thrust of his argument is that the irreligious Zionists who were building the State of Israel were, Kabbalistically speaking, higher order souls than the Jew who studied Torah and kept the Mitzvot. Moreover, he argues, that this is the case because they are part of the mystical 'light of the Messiah' and specifically because of their irreligiosity.
I would like to understand how this approach differs (if it does) from the Sabbatean mystical approach, championed by Nathan of Gaza (may his name be blotted out) and sourced in Lurianic Kabbalah, that sees sinning in the Messianic age as permissible and even preferable as a way to elevate hidden sparks of holiness captured by the forces of evil.
