If you are unhappy, that simply means that you have learned tricks for being unhappy. Nothing else! Unhappiness depends on the frame of your mind. There are people who are unhappy in all kinds of situations. They have a certain program in their mind that transforms everything into unhappiness. If you tell them about the beauty of the rose, they immediately start counting the thorns. If you say to them, "What a beautiful morning, what a sunny day!" they will say, "Only one day between two dark nights, so why are you making so much fuss?"
The same thing can be seen from a positive reference; then suddenly each night is surrounded by two days. And then suddenly it is a miracle that the rose is possible, that such a delicate flower is possible among so many thorns.
All depends on what kind of frame you are carrying in your head. Millions of people are carrying crosses. Naturally, obviously, they are burdened; their life is a drag. Their frame is such that it immediately becomes focused on everything that is negative. It magnifies the negative. That is a morbid approach towards life, pathological. But they go on thinking, "What can we do? The world is such."
No, the world is not such! The world is absolutely neutral. It has thorns, it has roses, it has nights, it has days. The world is utterly neutral, balanced - it has all. Now it depends on you as to what you choose. That´s how people create hell and heaven on the same earth.
