Acharya Prashant explains that all human thoughts are fundamentally rooted in the dimensions of space and time. He asserts that every thought relates to a memory, which is a record of the past, and involves forms that exist in space. He challenges the audience to think of anything outside these dimensions, noting that even abstract concepts like 'God' or 'nothingness' are often reduced to mental images or sensations that occupy space and time. He defines objects as entities existing within these two dimensions and identifies the brain as the material instrument used for perception. He further describes the brain as a material object susceptible to permanent or semi-permanent deformation by external experiences, a process he calls conditioning. Because of its material nature, the brain is constantly influenced by sensory inputs from the environment, functioning much like a pre-programmed machine or a computer hard disk. He distinguishes the brain from the mind, defining the mind as the combination of the brain and intelligence. While the brain follows automatic programming and lacks inherent understanding, intelligence is the capacity to understand what is happening and to recognize the brain's mechanical nature. Acharya Prashant emphasizes that intelligence is not derived from past experiences or information, as it must operate in the present to understand new, fresh moments. He argues that while a highly advanced robot can process data and follow complex programming, it lacks the intelligence to understand its own programming or act with free will. Intelligence operates only in an environment of total attention. It is the force that observes the mechanical stupidity and conditioning of the brain, responding with the principle of 'Neti, Neti'—meaning 'not this, not this'—to indicate that the truth lies beyond these material deformations.
