When we see something, instantaneously a thought forms in the mind. Objective Scientists have no tools to evaluate how the sensory input about the perceived object is transformed into thought in the mind. This aspect has been analyzed by our Vedic scholars. Dharmaraja Advarindra of the 17th century presented in his book ‘Vedanta Paribhasha’, how they analyzed this problem. This book provides a critical analysis of Vedanta Paribhasha dealing with how knowledge takes place in the mind from the perspective of a scientist and a Vedantin.
