We all are very familiar with this "superstitions". It is also known by some other names like "belief", fantasy', 'rumour', and so on. It is completely beyond or any logic. The science bluntly disapproves them. There are so many superstitions which have been with us since the beginning. They are different to the different people. We may be familiar with such superstitions. People act in some certain ways and try to come out from them.
As we know the superstitions exict with us. Some of them are as under. There are the superstitions about the birds, the animals, the colors, the God, the festivals and so on. There is a strange superstition about the black cat. In India people consider it as a bad luck. While in the parts of America people take it for granted as a good luck. Yet there is a superstition about the triangle. It is believed that if a person breaks the triangle by passing under it, it brings him a bad luck. There is the superstition about number 13. In the U.S.A. People believe this number to be very unlucky and therefore most of the buildings and offices do not have the floor number 13. After twelve they give the number fourteen. Moreover there is the superstition about the green color. Any actor or actress docs not use it while performing for the first time on the stage or in drama or in a movie. Mostly they put on or use saffron or red color for a good begining. There is a superstition about the dog's cry. It is believed in India that if a dog cries nearby someone's residence it means it shows the signs of death of someone. There is also another superstition about the bird albastros. The sailors used to believe that if such a bird flies over their ship it may bring ill-luck. Above mentioned superstitions and other superstitions have no logic nor the truth yet they cling to us. The science denies them completely but we, the people are habituated to them and in one or the other way we believe that by acting in certain ways. We can't escape from them though we wish or try. Gradually they are expanding rather than avoiding.
