Look not to addiction, but to addictive personalities. Such shackles of obsessive repetition are the beast's desire for the tedious. Freedom is painful to the beast, essential for the spirit. There is a constant conflict between the two - the illustration of the two-headed llama is apt.
The beast adores surrender to its nature. Higher nature works towards subservience to man, knowing inwardly that its future will is bound to that kingdom. But when man has not the power of will to guide the animal within, the beings of repetition bound closely to sub-physical desires and gratifications, sway the undiscerning into such obedience.
