The sense organs are under the influence of the psychological state of the individual because something comes in between the eye’s perception and the brain’s reception. It is very subtle; the brain receives the eye’s perceptions through the nerves; there is no reasoning, it is so to say instantaneous, but there is a short passage between the eye’s perception and the cell which is to respond and evaluate it in the brain. And it is this evaluation of the brain which is under the influence of feelings. It is the small vibration between what the eye sees and what the brain estimates which often falsifies the response. And it is not a question of good faith, for even the most sincere persons do not know what is happening, even very calm people, without any violent emotion, who do not even feel an emotion, are influenced in this way without being aware of the intervention of this little falsifying vibration.
At times moral notions also intermix and falsify the judgment but we must throw far away from us all moral notions; for morality and Truth are very far from each other (if I am shocking anybody by saying this, I am sorry, but it is like that). It is only when you have conquered all attraction and all repulsion that you can have a correct judgment. As long as there are things that attract you and things that repel you, it is not possible for you to have an absolutely sure functioning of the senses.
