Answer: In ancient times, there were many women who were Kabbalists, like Sarah, Rebecca, Rachel, Leah, Miriam, and so on. However, in the last 700 years, I cannot point to any woman who was on this level.
Question: But the wisdom of Kabbalah gives equal opportunity to all.
Answer: There was a time when there was no equal opportunity because Judaism was in darkness, in exile. True Judaism is derived from a yearning to attain and reveal the Creator, the desire to resemble Him—things that are attained through the connection between us. After the destruction of the Beit HaMikdash (Temple), we were in darkness, in unfounded hatred, distant, and lacking the understanding of where we were. We performed mechanical actions without knowing why and how. Today, these actions are called Judaism.
We exchanged the true learning, the Light, for requirements completely devoid of Light and attainment of the upper world, for incomprehensible interpretations.
For 2,000 years, we were living in a period that was like the Middle Ages, and it has been only in the last twenty years that the wisdom of Kabbalah has begun to be revealed gradually. An identical program for men and women exists with us the Bnei Baruch group. Both of these groups study identical courses. It is clear that the entire world needs to know the system of connection; otherwise, we cannot survive. So, women must participate in this because women influence the men, and it is necessary to use this to awaken them.
A man is like a little child. He is interested in soccer and a few other things, whereas a woman looks more soberly at life. So, we want to see serious participation from women.
