Baal Sulam. Preface to TES, p.147

"That's because there is no difference in what whatsoever between the Torah of Atzilut and the Torah of our world, that is, between Kabbalah and open Torah.

And all the difference is only in the human condition, to engage in Torah.

And over the years engaged in two people in the Torah is indeed one and the same law and the same language, but at the same time one will be the Torah - Kabbalah and the Torah of Atzilut, and the other is an open Torah of Assiya (our world).

And understand this well. "
