Sounds like the blind leading the blind to me. Whatever it is she's studying, is sure as shootin' ain't real Jewish mysticism. My guess is that its some sort of 'new age' thing with a veneer of terminology culled from authentic mysticism in order to try to get some respectability. From what I've heard about her, Ms. Lewinsky is not, to put it mildly, a scholar of Torah. Traditionally, to qualify to even study kabbalah, the person must have attained 40 years of age, and be well-grounded in scripture and the writings of the sages. Also married. I don't think she qualifies, on any count.
All religions have their 'mystical' aspect. Mysticism, rightly understood, is about attaining a greater intimacy with the divine. Islam has Sufism and various types of Shi'ism. Judaism has kabbalah, among other mystical traditions. Christianity has writers such as John of the Cross, Meister Eckhardt, Teresa of Avila and others. The language and teaching of mysticism is highly symbolic, and is intended to point to the Reality beyond language.
