There are three things: World, Torah, and man (The Zohar, Toldot¸ Item 2).
The world means Malchut.
The Torah is the light of Torah, which reforms a person.
Man is placed under the Klipot [shells/peels] for thirteen years, and after thirteen years he enters Kedusha [holiness]. By the power of the Torah he can invert the will to receive into a desire to bestow.
