Acharya Prashant explains that feelings are not abstract but are essentially thoughts that manifest as physical sensations in the body. He clarifies that the word 'abstract' actually means 'essence' rather than something incomprehensible. He asserts that concepts like 'ever', 'never', and 'happening' are rooted in time and space, and that the human mind operates within these dimensions. He defines the 'I' or the sense of self as the mind in operation, noting that this sense disappears when the brain enters sleep mode. He emphasizes that the brain is a product of millions of years of evolution, shaped by external influences and experiences stored in the DNA. Acharya Prashant further describes the brain as a biological machine programmed by the past to perform automatic functions like breathing and heart regulation. He introduces the formula that the mind is the sum of the brain and intelligence. He explains that the brain's very nature is to be influenced by external objects because it is constructed from the sum total of those historical influences. This process of being shaped by external factors is what he terms 'conditioning'. He concludes that because the brain is a product of space and time, it is naturally prone to being dominated by the objects and experiences it encounters.
