(This explains matters corresponding to the Sefirot and the interrelationships between them.)
98. There are five general levels of the soul; Nefesh, Ruach, Neshamah, Chaya, and Yechidah. Each of these subdivides into five subsequent levels, as follows; Nefesh of Nefesh, Ruach of Nefesh, Neshama of Nefesh, Chaya of Nefesh, and Yechidah of Nefesh. This principle applies to all five general levels. These five levels correspond to the Sefirot as follows;
Nefesh corresponds to Malchut,
Ruach, to the six Sefirot of Zeir Anpin,

Everything that exists has a correlation to one or more of the Sefirot. This includes animal, vegetable and mineral, as well as the sequence of time. Each millennium in history corresponds to a specific Sefirah. Since the mitzvot also correspond to the Divine conducts, each one affects its respective Sefirah.
103. Through the contemplation of three matters; the order of the worlds, the concept of time, and the nature of man, one may arrive at an understanding of the Divine conducts. In Sefer Yetzirah these are called “World”, “Year”, and “Soul”, (עש”ן or עולם שנה נפש).
(104, 105, and 106 are redundant in that they are charts of the above. Therefore, they have been omitted)
 Sefer Yetzirah, Chapter 4 and commentary of Gra there.
 Even though there are more heavenly bodies, nonetheless these are the essential ones to astrology since they may be observed by the naked eye.
 The word Aravot is plural and therefore represents several sefirot.
 The word Shechakim is likewise plural. It therefore represents two sefirot.
 Sefer Yetzirah, Chapter 4.
