Our point of view is that, as with anger, drugs would tend to diminish the precision of a warrior's actions. The secret of the berserk's invulnerability is the ability to let the True Will flow unimpeded. This requires the warrior to be totally calm and centered while at the same time unleashing the destructive forces of the Will. The slightest distracting thought can be fatal. By not letting thoughts interfere with the flow of Will, the berserk is always in the right place at the right time.
Action flows, there is no rigidity or predictability, there is nowhere a blade can strike.
The berserk acts without hesitation and is always in harmony with any situation. Harmony in this case means being true to the self and interacting with the situation in a way which is honest with the self. This can only be done when there is no barrier between the self and the situation. One becomes a fluid part of the situation without losing one's individuality, an indispensable and autonomous part of the whole, every movement being a vital adjustment of one's position in the universe.
