This scholarly treatise on the Science of Omens by Dr. Bhojraj Dwivedi, is a unique work encompassing the essence of the study done on this occult branch of knowledge by our ancient seers with a modern, science based interpretation. The events that forewarn or foretell the future happening, are not based upon blind superstition but on a very keen observation of the behaviour of the animals, birds etc. whose perception in detecting effect these happenings is much sharper than of that of the human beings.
