It all began with me and my wife going in to a restaurant previous weekend when I was visiting her. There we chanced upon the Chinese predictions for the people born under the signs of various animals. For the uninitiated it is important to know that like all ancient cultures Chinese also follow a calendar based on Moon and each year is named after an animal in a predefined set of animals. The people born in these years are thought to manifest the nature ascribed to the animal.
Then, when we were through our dinner, my wife started asking why snakes are considered wise beings? I did not have a definitive answer. Today suddenly a moth fell in to the glass of milk I was drinking and died. It made me look through the symbolic meaning. While looking at that, i read about snakes open hood being used as a symbol of offense by Egyptian pharaohs. in Hindu mythology lord Vishnu sleeps on a bed formed by the curling body of 1000 hooded serpent named Adishesha. Here, snake with open hood is a symbol of security and shelter.
Suddenly it flashed to me that the opened hood of a cobra very gracefully combines both the offensive and defensive natures. It is what the rulers must do and must be like. Punish the wrong doers and protect the pious. It is what the wise people do.
Now I believe I know why snakes and among them the cobra is held in such high regard.
