Who Is a Kabbalist?
Now we can easily understand the merit [special quality and wisdom, heart and mind] of one who has been rewarded with cleaving unto Him once more. It means that he has been rewarded with equivalence of form with the Creator by inverting the [egoistic] will to receive, imprinted in him through the power in Torah [the Light of correction] and Mitzvot. This was the very thing that separated him from His Essence [absolute good and bestowal], and turned it [specifically his ego] into a will to bestow.
And all of one’s actions are only to bestow and benefit others [in which he is similar to the Creator], as he has equalized his form with the Maker. It follows that one is just like the organ that was once cut off from the body and has been reunited with the body: It knows the thoughts of the rest of the body once again, just as it did prior to the separation from the body.
The soul [the point in everyone’s heart, the aspiration for the Creator after it awakens in a person] is like that, too: After it has acquired [by correcting itself via the Light] equivalence with Him [acquired the quality of bestowal in place of its inherent quality of reception], it knows His Thoughts [as it knows its own for it has achieved adhesion with Him] once more, as it knew prior to the separation from Him due to [uncovering] the will-to-receive’s disparity of form [being opposite to the qualities of the Light, the Creator].
Then the verse, “know thou the God of thy father,” lives in him, as then one is rewarded with complete knowledge, which is Godly knowledge. Also, one is rewarded with all the secrets of the Torah, as His Thoughts are the secrets of the Torah. [“Secrets” refer to the Creator’s thoughts and desires because they are concealed from a person due to disparity of form and are attained by him as he becomes similar to the Creator.]
