Acharya Prashant explains that the senses and their objects collectively constitute the world, and the division we create between the 'internal' senses and the 'external' world is a construct of the ego. He clarifies that the interaction between senses and objects is a purely physical and chemical process governed by nature, much like chemical reactions. The ego, however, falsely claims ownership over these sensory experiences, leading to suffering. He emphasizes that the senses operate based on deep-seated biological programming and evolutionary instincts, such as seeking nutrition or safety, which have nothing to do with the individual's consciousness or soul.
