Torah refers to the Light clothed in the Torah, 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.
– Baal HaSulam, Shamati (I Heard), Article no. 6, “Support in the Torah”
The Torah is the only spice to annul and subdue [stop using] the evil inclination [man’s egoism], as our sages said, “The Light in it reformed them.”
