Only the Light in the Torah Reforms the Person
Torah refers to the Light [of correction] clothed in the Torah [in the aspiration to reach the property of bestowal by connecting with the friends, to be as one], meaning, as our sages said, “I have created the evil inclination, I have created the Torah as a spice.” This refers to the Light in it, since the Light in it reforms it [creates within a person the property of bestowal].
– Baal HaSulam, Shamati [I Heard], Article No. 6, “What Is Support in the Torah in the Work”
The Torah is the only spice to annul [to correct by the upper Light] and subdue [to replace man’s nature with the opposite nature, that of the Creator, to shift from egoism to bestowal and love] the evil inclination, as our sages said, “The Light in it reformed them.”
