There are two kinds of knowing – experience and understanding – and the confusion between them is the cause of all sorts of trouble for any thinking person – which is all of us.
Experience is the knowing of things. It is exactly what appears to our senses precisely as it is without us doing anything. It is immediately and directly present to awareness with no mediating activity. Because it is immediate it cannot be denied.
Understanding is the knowing about things. It comes to us in the form of the inner language of thought.
Understanding is the knowing-about-things that is contained in explanations, interpretations and logic.
Reason is intuitive knowing. It is the self evident knowing that isn’t derived from rational deduction. It is directly perceived pure awareness.
