The word "shakun" (omen) signifies a bird. Previously, only birds were used to detect omens and bad omens. Later, other animals were also included in this category. According to scholars, "the auspicious sign of the completion of a work is called an omen." Also, the cycle of good and bad events is always going on. Based on these incidents, a man gets good omens and bad omens.
Many animals and elements of nature make us cautious by expressing their previous actions. Before earthquakes, tsunamis, storms, etc., animals start screaming in panic, and in this way they alert us. In ancient times, by observing these signs minutely, sages and scholars created the "Omen Shastra," which is equally authentic and a subject of deep study even today. The current events and their subtle effects begin to fall on the people of the earth, particularly the living beings because they are directly related to nature. This is why, by observing their expressions, habits, and behaviors, one can determine whether the omen is auspicious or inauspicious.
Omen is also discussed in Hindu religious texts such as the Mahabharata, Vedas, Puranas, and Ramcharitmanas. These are said to be of three types: auspicious, inauspicious, and mixed. Everything is auspicious in an auspicious omen, everything is inauspicious in an inauspicious omen, and good and bad mixed results are found in a mixed omen.
Indian mystics studied the various actions, activities, and efforts of birds in minute detail and compiled the knowledge gained from them in the form of scripture. Later, this science was expanded by including incidents related to animals, aquatics, humans, and plants. Later, this scripture became famous under the name "Omen Shastra." This book has been written on the subject of ancient omens. We leave it to the readers to take it that way. We hope you will find it useful as well as interesting and will benefit from it.
