If you are unhappy, that simply means that you have learned tricks for being unhappy, and 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 quality in their mind which 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 look at you as if they are surprised by your statement. They will say, "So what! One day between two dark nights! It is only one day between two dark nights, so what is the big deal? Why are you looking so fascinated?"
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.
Everything is the same. All depends on what kind of frame you are carrying in your head.
