"...We are in a very strange state because positive emotions don't belong to our ordinary emotional centre but to higher emotional centre and negative emotions don't belong to this ordinary centre but exist in an artificial centre. So our emotional centre is neither positive nor negative and higher emotional centre has no negative emotions. Negative emotions are some kind of artificial creation. How are they created? The emotional centre borrows material from the instinctive and with the negative part of the instinctive centre and the help of imagination it creates negative emotions. They can be destroyed exactly because they have no real centre. This is very difficult work but you must realize that as long as negative emotions exist no development is possible because development means development of all that is in man. Negative emotions cannot develop it would be very disastrous for us if they could. So if one is trying to create consciousness one must at the same time struggle with negative emotions..."
