613 Suggestions and 613 Deposits
In several places in The Zohar, he calls the 613 Mitzvot, “613 counsels” [of how to correct the Kli] and in many other places in The Zohar he calls the 613 Mitzvot, “613 deposits” [the Lights that have to enter the corrected Kli]. This is so because at first, one must keep the Torah and the Mitzvot in order to refine his body [himself from egoism] and enhance his soul [the aspiration for bestowal and love].
At that time, the 613 Mitzvot are as 613 counsels [this type of correction] for him, “suggestions” by which to gradually refine and be awarded coming before the King [rising above egoism], and receiving the Light of his face. This is because keeping the Torah [attracting the Light] and Mitzvot [correcting 613 egoistic desires] gradually purify him [from natural egoism], until he is rewarded with the Light of the King’s face [the general, universal property of bestowal and love]. [Otherwise, there is no use of his actions.]
Also, it is written similarly in the Gemarah: “The Creator cares not if one slaughters at the throat or slaughters at the back of the neck [meaning that mechanical actions in and of themselves do not carry any meaning]? Rather, we were given the Torah and Mitzvot only to purify Israel [those who strive for the Creator, the property of ‘love thy neighbor as thyself’].”
However, after one has been sufficiently purified [from egoistic desires] and merits the Light of the King’s face [the property of bestowal], one’s eyes and soul [the will to bestow] open and he is awarded the attaining [within himself] the 613 Sacred Lights found in the 613 Mitzvot [corrected desires]. These are His Holy Names [attainment thereof], the ones he can attain.
By keeping each of the Mitzvot [correcting each desire], one takes [receives into it] the part of the Light deposited in that Mitzva since the Mitzva is a Kli (vessel) [desire] where the Light is clothed, meaning a Holy Name [His individual property] that belongs specifically to that Mitzva. This is the meaning of “The Mitzva is a candle and the Torah—Light.” At that time, he calls the 613 Mitzvot “613 commandments (deposits).”
