Acharya Prashant explains that the nature of the brain is to be influenced by external objects, a process known as conditioning. He categorizes conditioning into two types: physical conditioning, which is inherited from thousands of years of evolution, and social conditioning, which occurs during one's current lifetime. The brain is characterized by having nothing of its own, being purely borrowed, prone to external influences, and existing strictly within the dimensions of time (past and future) and space. In contrast, intelligence is original, cannot be influenced by external factors, operates in the present moment, and understands the 'here' rather than being lost in 'space'. He further describes thoughts as the brain's tendency to exist in time and space, noting that thinking and understanding cannot happen simultaneously. While the brain takes an individual into an alternate virtual reality of memories and hopes, intelligence allows one to understand the present moment. The brain's primary agenda is survival, leading it to project favorable past experiences into the future as hopes and unfavorable ones as insecurities. Acharya Prashant emphasizes that living purely through the brain's programming is mechanical and akin to the life of an animal or a machine. True human potential is realized only when intelligence finds expression, allowing an individual to go beyond their biological and social programming.
