What I said that Rab Dessler took it from Rab Ashlag I red in a book that is a biography and the main teachings of Sulam, and it said there "Rab Dessler used this concept, as it is well known". The book was in hebrew. I saw it in the sinagogue of Ramada Hotel Yerushalaim.<div>
<br></div><div>Micha: what you said that Baale mussar didn't use Kabalah is completely incorrect. It just that they didn't EXPLICITLY quote from there, but they did it IMPLICITLY. Those who understand, understand.</div>
<div><br></div><div>Examples: Rab Itzchak Hutner, Rab Dessler, Sama miKelm, The Bloch's Rabbi from Telsh, Rab Zaichick, all of them ZT"L, and others that I don't have in mind right now.</div>
