Now, each distinction and grade of the three— nefesh, ruach and neshamah— consists of ten faculties, corresponding to the Supernal Ten Sefirot (Divine manifestations), from which they have descended, which are subdivided into two, namely, the three "mothers" and the seven "multiples," to wit: chochmah (wisdom) binah (understanding) and da at (knowledge); and the "seven days of Creation:" chesed (kindness), gevurah (power), tiferet (beauty), and so on.

Similarly is it with the human soul, which is divided in two— sechel (intellect) and middot (emotional attributes). The intellect includes chochmah, binah and da at (ChaBaD), whilst the middot are love of G‑d, dread and awe of Him, glorification of Him, and so forth. ChaBaD [the intellectual faculties] are called "mothers" and source of the middot, for the latter are "offspring" of the former.

The explanation of the matter is as follows:

The intellect of the rational soul, which is the faculty that conceives any thing, is given the appellation of chochmah—כ"ח מ"ה— the "potentiality" of "what is." When one brings forth this power from the potential into the actual, that is, when [a person] cogitates with his intellect in order to understand a thing truly and profoundly as it evolves from the concept which he has conceived in his intellect, this is called binah. These [chochmah and binah] are the very "father" and "mother" which give birth to love of G‑d, and awe and dread of Him.

For when the intellect in the rational soul deeply contemplates and immerses itself exceedingly in the greatness of G‑d, how He fills all worlds and encompasses all worlds, and in the presence of Whom everything is considered as nothing— there will be born and aroused in his mind and thought the emotion of awe for the Divine Majesty, to fear and be humble before His blessed greatness, which is without end or limit, and to have the dread of G‑d in his heart. Next, his heart will glow with an intense love, like burning coals, with a passion, desire and longing, and a yearning soul, towards the greatness of the blessed En Sof. This constitutes the culminating passion of the soul, of which Scripture speaks, as "My soul longeth, yea, even fainteth,.. ." and "My soul thirsteth for G‑d,..." and "My soul thirsteth for Thee...." This thirst is derived from the element of Fire, which is found in the divine soul. As students of natural science affirm, and so it is in Etz Chayim, the element of Fire is in the heart, whilst the source of [the element of] Water and moisture is in the brain, which is explained in Etz Chayim, Portal 50, to refer to the faculty of chochmah, called "The water of the divine soul." The rest of the middot are all offshoots of fear and love and their derivations, as is explained elsewhere.

Da'at, the etymology of which is to be found in the verse: "And Adam knew (yada) Eve," implies attachment and union. That is, one binds his mind with a very firm and strong bond to, and firmly fixes his thought on, the greatness of the blessed En sof, without diverting his mind [from Him]. For even one who is wise and understanding of the greatness of the blessed En Sof, will not— unless he binds his knowledge and fixes his thought with firmness and perseverence— produce in his soul true love and fear, but only vain fancies. Therefore da'at is the basis of the middot and the source of their vitality; it contains chesed and gevurah, that is to say, love with its offshoots and fear with its offshoots.
