One useful way to approach the more violent aspects of chapter III is to view it as the essential spirit of the pre-adept work. It is war with the inertia of the elemental self, that will drag you down unless you stand your ground and fight. (AL III:4-9) Mercy and pity won't help you in the battle (AL III:18) as you struggle with your own ill ordered house (your self). The work may become distasteful and is not entirely risk free. Ra-Hoor-Khu is with thee. (AL III:11)
When considering the god RHK it is helpful to study Atu XVII The Tower (War) and Atu VIII Adjustment (Vengeance). As the tutelary deity symbolic of the True Will he is an energizing and balancing force,
provided you are in alignment with him.
If there are blockages to the True Will then he
appears destructive and his means of balancing the scales is Geburah (see the 5's of Tarot).
