Now if we examine our life, our relationship with another, we shall see that it is a process of isolation. We are really not concerned with another; though we talk a great deal about it, actually we are not concerned. We are related to someone only so long as that relationship gratifies us, so long as it gives us a refuge, so long as it satisfies us. But the moment there is a disturbance in the relationship which produces discomfort in ourselves, we discard that relationship. In other words, there is relationship only so long as we are gratified. This may sound harsh, but if you really examine your life very closely you will see it is a fact; and to avoid a fact is to live in ignorance, which can never produce right relationship. If we look into our lives and observe relationship, we see it is a process of building resistance against another, a wall over which we look and observe the other; but we always retain the wall and remain behind it, whether it be a psychological wall, a material wall, an economic wall or a national wall.
So long as we live in isolation, behind a wall, there is no relationship with another; and we live enclosed because it is much more gratifying, we think it is much more secure. The world is so disruptive, there is so much sorrow, so much pain, war, destruction, misery, that we want to escape and live within the walls of security of our own psychological being. So, relationship with most of us is actually a process of isolation, and obviously such relationship builds a society which is also isolating. That is exactly what is happening throughout the world: you remain in your isolation and stretch your hand over the wall, calling it nationalism, brotherhood or what you will, but actually sovereign governments, armies, continue. Still clinging to your own limitations, you think you can create world unity, world peace - which is impossible. So long as you have a frontier, whether national, economic, religious or social, it is an obvious fact that there cannot be peace in the world.
