Kabbalah refers to spiritually deep understanding in Judaism, and even Jews are discouraged from studying it until they are deemed mature enough to handle the subject. Jewish law also forbids men from hearing a woman sing. Therefore, Madonna’s concert appearances in Israel are against Jewish law, said Rabbi Batzri, head of the Shalom Yeshiva in Jerusalem.

“No one can study Torah unless he or she is converting to Judaism," he explained to Arutz-7's Hebrew news site. Madonna’s ostensible plunge into Kabbalah several years has been widely condemned by Torah scholars. Rabbi Batzri said Sunday, however, “There is no connection between what the singer learns and true Kabbalah. The foundations of Kabbalah are the Tree of Life…that no one can learn without abstention.”

He added that learning Jewish mysticism is a spiritual path towards “practical Kabbalah” and that learning it means one must act against certain natural instincts. Madonna’s performances are stacked with sexual innuendoes; her private appearance for Rosh Hashanah, the Jewish New Year, two years ago was met with disgust by rabbis and Jewish thinkers.
