Acharya Prashant explains that the fundamental drive of all biological entities, from viruses and bacteria to humans, is self-preservation and self-propagation. He illustrates this by comparing a virus, which infects a host to multiply regardless of the host's suffering, to a factory owner who pursues profit despite the environmental damage and health risks to others. Both operate from the same core of self-interest. He emphasizes that humans often condemn a virus while respecting a wealthy industrialist, even though their underlying motivations and consequences—such as damaging lungs—are identical. True liberation comes from observing these natural movements without interference, realizing that the body is part of a larger system that functions on its own, much like a river flows without effort.
