N. Sivasubramanian (b.1936) has been a student of physics, engineering, law and philosophy and pondered for almost 47 years over the revelations of many spiritually realized sages about the spiritual origin of person. The absence of a belief in the spiritual origin of the person in the life sciences, and also in the social sciences, was puzzling and it forced the author to delve into scientific findings in neuroscience. The study did not show how bio sciences can progress without acknowledging the spiritual origin of person, the living being. The effort then was to try and explain experimental facts especially in neuroscience and also in physics without closing one's eyes to the reality of the spiritual origin of the scientist. He or she creates in mind the scientific theories and outlooks. The result was the writings called 'Science of Person'. It is published in the hope it may interest a few others who have also enquired on similar lines in their minds or may like to do so after reading the publication.
