I am often asked the question about whether someone needs to be 40 yrs old and learned in Talmud and Halakha before they can learn the Kabbalah. Unfortunately, this is a grave misconception by most.
It is true that having a knowledge of the revealed Torah, like Talmud, Halakha, and Tanakh is preferable, but not a prerequisite. I think the misconception is the result of not understanding the difference between what is called "Sitrei Torah" and Ta'amei Torah." The first is the secrets of Torah, and the second is the tastes, intentions, or reasons of the Torah.
An example of the Sitrei Torah would be discussing Maasei Merkavah or Maasei Bereshit. These are the workings of the Divine Chariot and the workings of Creation. These are left to only those who are the most wise of our sages to pass down to their students. However, the tastes or reasons of Torah are meant for everyone to learn.
As a matter of fact, the Baal HaSulam, Rav Ashlag taught that to ignore the Ta'amei Torah was to hold back Moshiach. Let us be people who desire to learn the tastes or intentions of Torah for the right reasons. Not for selfish reasons, but only to bring pleasure to our Creator. To be those who want to receive, only in order to give.
