Mashiach-er-Madonna is Coming. . .

(le-havdil*.)
This is a sign of the times. Madonna has come to tour the Holy Land (again). The interesting thing is, that she, The Material Girl has, as have some other celebrities over the years, found a fascination with Kabbalah and things Jewish, while many Jews never had or even worse, have lost their connection to Judaism.
Instead, they drift into the secular, spiritually purposeless lifestyle of our prevaling culture. As Rabbi Yitzhak Batzri--with whom I don't agree on everything he says, but do on this--stated on this latest visit by Madonna (oh, excuse me: by Esther):

“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.

Here is the long and short of it. One is not permitted to 'learn' Torah for frivolous reasons. If one is really serious, one should "leave the institutions that capitalize on the trend" (of kabbalah), and instead, as Rabbi Batzri puts it, "look for a true way to Judaism:"

There is another way to look at it though. Maybe this trend of Judaism's growing popularity among non-Jews is indicative of the fact that the Mashiach is really coming (bi'mehayrah be-yamenu, Amen*.)

*le-havdil: lit., 'to separate,' not to equate the two
*Mashiach: the Jewish Messiah
*bi-mehayrah be-yamenu: quickly, in our time
