“Anger has its place, but it will not serve you here, the way of the warrior is the way of knowing. Of that knowledge requires you to use anger, then you use anger, but you cannot wrest forth knowledge by losing your temper.”

“Some knowledge is too heavy...you cannot bear it...your Father will carry it until you are able.”

“Perception is blind to the knowledge that you cannot understand.”

“Knowledge is invariably a matter of degree : you cannot put your finger upon even the simplest datum and say 'this we know'.”
