After all, it isn't the facts of one's environment, but one's attitude toward them, that determines whether one will be defeated or victorious.

~ David Hawkins

Perceptual fields are limited by the attractor patterns that they're associated with. This means that the capacity to recognize significant factors in a given situation is limited by the context that arises from the level of consciousness of the observer. The motive of the viewer automatically determines what is seen; causality is, therefore, ascribed to factors that are, in fact, a function of the biases of the observer and aren't at all instrumental in the situation itself.
