Acharya Prashant explains that human attraction and the definition of beauty are fundamentally driven by biological instincts and the forces of Nature. He points out that women are naturally drawn to muscular men because physical strength and high testosterone levels are indicators of reproductive health and the ability to produce offspring. Similarly, men perceive certain physical features in women as beautiful because those traits signify fertility and the capacity for childbirth. He argues that what people call love is often an unconscious biological drive to find a fertile partner, a process orchestrated by Nature without the individual's conscious awareness. He further discusses the concepts of commitment and loyalty, suggesting they are mechanisms to ensure a guaranteed and uninterrupted supply of physical intimacy to satisfy biological urges. Acharya Prashant asserts that Nature's primary objective is the continuation of the species rather than monogamy. He explains that because the biological drive is focused on reproduction and satisfying hunger rather than a specific person, behaviors like adultery become common. He concludes that human desires are largely trained by Nature to simply appease physical hunger and thirst, regardless of the individual involved.
