Acharya Prashant explains that human conditioning occurs through two primary mediums: physical and social. Physical conditioning is embedded in our DNA through millions of years of evolution, meaning no child is born as a truly blank slate. Social conditioning begins immediately after birth. He clarifies that it is impossible to be completely free from external influences because the 'outside' world is always present, whether one is in a hall or on a mountain peak. This external influence is necessary and inevitable during childhood because the brain is not yet fully developed, and a child must rely on others for survival and basic knowledge.
