" …Visualize that you are sitting in a room and there are many windows. One window is sadness – you open it and you become sad. You are not sadness – the scene opens on sadness. You can open the window of anger, and you become angry. You can open the window of love, and you become loving. You can close all the windows and sit there. This is what eastern meditation is - close all the windows and sit there. 
Negative windows have to be opened first, because society has closed them, and people have completely forgotten how to be angry. If you don’t know how to be angry, how can you know how to be in compassion? It is impossible. Compassion is a higher state and you have not even fulfilled the preliminary. The first step has not even been taken, so how can you take the last? 
You move to anger. You open the window and go as far as you can so that you are finished with it. When you are finished with it, you are ready to open the door of compassion. It is exactly the opposite window. Once all that society has repressed surfaces – is relieved – you are cleansed. Once a person is cleansed, he will automatically start moving towards the positive windows. 
Take his hand and lead him towards the window and he will move – because nobody wants to hate. Nobody wants to be angry, because one suffers through it. Everybody wants to love and to be loved. Everybody wants to live as beautiful a life as possible. One lives an ugly life, because one does not know how to live a beautiful life. One dreams about the beautiful and lives the ugly. The ugly has been repressed and that repression has culminated and corrupted the whole being, so that it becomes almost impossible to reach the higher dimension..."
