Competence brings about dimension, and dimension is harmonious, distorted, crowded or majestic, colorful or drab, bright or boring, according solely to the exercise of vision.
Complaint is an offense because it is a bamboozle. Complaint is a statement that some condition, way of being, feeling or other aspect of dimension is operating other than the Source wishes it to. All complaint is confession.
Imagine the picture of a thin and limp-wristed artistic playwright, weeping in his sushi because the characters in the third act aren't coming out the way he wants them to. They just won't cooperate, he complains.
Who does he think he is? Creating characters that won't co operate is a confession of his own belligerence with himself.
