This discourse was said by the Rebbe on Shabbat Tetzaveh in 1965.  Does the oil have to be extracted from the negativity of the bitter olive, or does it naturally descend from the exalted olive of supernal Wisdom?

This seemingly abstract discussion leads to a presentation of two dimensions in life: the higher level, at which Moses (and his successors, leaders of the Jewish people) draw the oil of selflessness and supernal repentance, the oil of Torah, and transmit it below to Aaron and the Jewish people, who struggle to remove the pure oil from the concealing olive and use its radiance to light up the world.
