Psychochemistry: the science of human interactions and relations Mukta Sharma 1 , R. S. Kaushal 2 *, D. Parashar 3 ABSTRACT We use a Vedic framework to understand the entire gamut of psycho-processes at the most fundamental level that take place not only in each of us but also among us with reference to human relations and interactions. For this purpose, we explore here a philosophical atom-like (called the ‘patomic’) model of human Beings. This model, inspired from the philosophy of Srimad- Bhagvad-Gita, has bearing on some undeniable essences of life (EOLs) that we all carry till our death. As a matter of fact, these EOLs actively participate not only in establishing relations but also in interactions with other Beings and with the Nature as a whole. The concept of dressing of EOLs with the consciousness of an individual further adds new dimensions to these studies, particularly in fine-tuning the analysis of these psycho- chemical reactions. Here, instead of exchange of charged ions (as in atomic chemistry) or of colored ions (as in color-quark-chemistry) the exchange of ‘tanmātrās’ is considered. Attempts are also made to analyze the interactions taking place between two-, or among three- or many-human-Being systems within this framework. To this effect analogies from the theories of physics and chemistry are frequently borrowed wherever considered appropriate. These studies are expected to help in an all-round development of the personality of a person on the one hand and of a family or a society on the other, since the latter basically are the collective versions of individuals. Several examples are cited and representative cases are analyzed. Keywords: Essences of Life, Patomic Model, Dressing Rules, Human Interactions and Relations INTRODUCTION Psychophysics and Psychochemistry The subject of Physics basically deals with the theories of existence of matter, its structure and sub-structures and the associated interactions (energy) to this effect at different space- time scales. The subject of chemistry, on the other hand, deals with the theories of co- existence not only of different species of matter but also of their constituents. All this pertains to the inanimate matter, describable successfully in terms of space-time structure of 1 Department of Chemistry, FET, Manav Rachna International Institute of Research and Studies, Sector 43, Faridabad, India 2 Formerly UGC Research Professor, Department of Physics & Astrophysics, University of Delhi, India 3 Formerly Associate Professor, Department of Physics, ARSD College, University of Delhi, Delhi, India *Responding Author Received: February 10, 2020; Revision Received: March 23, 2020; Accepted: March 29, 2020
