Theory:

A superstition is a belief as a result of ignorance, worry of the unknown, trust in magic or chance, or a fake idea of causation or an irrational abject attitude of thoughts towards the supernatural, nature, or God on account of superstition.
 
Superstitious beliefs were shown to help promote an excellent intellectual mindset. However, they can result in irrational decisions, which include trusting in the merits of exact good fortune and destiny rather than sound decision making. Duttada's wife, brother, and relatives from the lesson "The Comet II" were the finest examples of superstitious believers, believing that a comet might be controlled by a yajna.
 
Even if beliefs have shown variation from person to person, they have also some common aspects. Superstitions which we were able to collate are listed hereunder:
Example:
One cannot eat meal by putting his one foot over another, it means disrespect to the table and it is considered as the sign of famine. 
 
A mirror which is broken may bring bad luck; it is said,  house where mirror was broken cannot get well for a period of seven years.
 
When a black cat passes in front of a man, it is considered as ill-omen.
