It is known that the meaning [essence] of the souls of the children of Israel [those who aspire to the Creator, regardless of corporeal origin] is that they are a part of God Above [the property of bestowal]. The soul cascaded [diminished its property of bestowal] by way of cause and consequence and descended degree-by-degree until it became suitable to come into this world and clothe the filthy [egoistic] corporeal [desire to receive everything] body.
By keeping the Torah [studying to draw the Light of correction] and observing its Mitzvot [creating the group through Arvut, a mutual guarantee, the condition to receive the Torah] it ascends degree-by-degree [in acquiring the quality of bestowal] until its stature is completed [all 613 egoistic desires are corrected], and it is fit to receive its reward from The Whole [the Creator, who is completely giving and loving]. This has been prepared for it in advance [in the Thought of Creation], meaning attaining the holy [holiness = bestowal and love above one’s own benefit] Torah by way of the Names of the Creator [His qualities, that is, similarity to Him], which are the 613 deposits.
