I was wondering whether I could find a book which describes the stages of the seder hishtalshelus.
The Seder Hishtalshelus refers to the chain-like descent of spiritual worlds (Olam/Olamot) between God and Creation. It is part of Kabbalah.
There's a letter from the sixth Lubavitcher Rebbe concerning the four world's (Atzilut, Beriah, Yitzira, and Asiyah) that described this process in detail. It has been translated as part of the Chassidic Heritage Series with copious footnotes and can be found here :http://store.kehotonline.com/mobile/prodinfo.asp?number=efr-four
I'm sure it's also available on Amazon.com
You could try Section 2, chapter 1, "How Providence Works" from Derekh Hashem, (The Way of God) by the Ramchal.
