This work presents the Ancient Indian views on physics describing the methodology of science and elaborating the concepts of physics and neurology. This is an analysis and combination of two scientific disciplines of knowledge: physics and neurology. Soul or atman and ego or manas are universally accepted as metaphysical quantities. However, this work establishes atman and manas as physical quantities.It has been amply deliberated as to how the ‘I’, the ego, or manas interacts with the consciousness or self, the atman. Besides, the locations of atman and manas in the body have also been pinpointed and analyzed with the help of Tantra scriptures.Based on the vaisheshika and physics, the work deliberates the physical quantities of vaisheshika with special refernce to physics. The work breaks new ground and sets us thinking and wondering about the rediscovery of what already existed centuries ago. The book makes interesting reading and, paradoxically enough, leaves us baffled yet excited.
