== The Three Impure Kelipot ==
The three impure kelipot are the general life-force of the seventy ministers, from which all prohibitions, impure animals, and lands of the gentiles receive their vitality.

These kelipot are completely evil and have no good in them at all, therefore they can never be elevated. It is understood that their correction is only through breaking and nullifying them and removing them from the world.

=== ABYA of Kelipot ===
The Ramaz wrote on the Zohar that kelipat nogah is like the Keter for the three impure kelipot. And Torat HaChassidut explains that kelipat nogah is the aspect of 'atzilut' of kelipah and the three impure kelipot themselves (stormy wind, great cloud, and flashing fire) are briah, yetzirah, asiyah of kelipah. That is, just as the drawing down of the vitality of kedushah in the worlds of BYA is possible only through atzilut (which is the intermediary between the Ein Sof and the created beings), so too the impure kelipot cannot receive vitality except through kelipat nogah.

And one of the matters in this in avodah is that if a person prevents himself from permitted desires (kelipat nogah), automatically the impure kelipot (prohibitions) will have no place to grasp onto him at all.
