הֲל֨וֹא כֹ֧ה דְבָרִ֛י כָּאֵ֖שׁ נְאֻם־יְהוָ֑ה וּכְפַטִּ֖ישׁ יְפֹ֥צֵֽץ סָֽלַע׃ (ס)
La mia parola non è come fuoco? Dice l'Eterno; E come un martello che spezza la roccia a pezzi?
Derech Etz Chayim (Ramchal)
...Behold, that goodness is in his hands and he controls the decision, whether to educate himself and understand or to remain naked of all wisdom, even though the heart and mind are contained within his body. It is readily apparent that there are two things created sharing similar functions: Man's intellect and and The Torah that imparts the intelligence. With regards to The Torah it is stated (Jeremiah 23:29): "'Is not My word like a fire?', says Hashem." He made it known to us, the truth of the matter, that The Torah is literally like a singular light given to the Jewish people to find illumination with, not like other foreign wisdoms and secular information which are merely facts which can be comprehended though intellectual toil. However, The Torah is divinely holy whose existence is elevated in the highest heavens. When a person involves himself in The Torah below (this world) it illuminates his soul granting him access to lofty treasures, treasures of The Creator, in a reciprocating manner. As man works to understand The Torah works to change man.

As previously mentioned, in the dance of the flame different colors become apparent and so too there are big ideas included in this flame of light. Another idea expressed in the flame is the varied perspectives in Torah. It has been accepted by the Kadmonim that each root of the souls of Israel is contained within The Torah so that there are six hundred thousand explanations to the Torah corresponding to the six hundred thousand root souls. This is the idea of The Torah bursting into sparks. At first the light (Torah idea) ingnites to reveal all the different lights regarding the matter at hand. In turn each of those lights themselves illuminate a path within the six hundred thousand perspectives of the six hundred thousand souls of Israel. This is the secret of the verse (Jeremiah 23:29): "... and like a hammer that breaks the rock in pieces?" Although The Torah is infinite as well as each letter contained within, it is necessary to the fan the flame and then it will ignite.
