Acharya Prashant distinguishes between necessity and desire by observing nature. He explains that animals and natural elements like the wind act without doubt or the need for decision-making because their actions are an inseparable part of their existence. Necessity is defined as that which must happen and does not require the sense of a doer or intellectual deliberation. In contrast, desire arises from the ego and involves conflict, thought, and multiple choices. While physical functions like breathing are necessary and unstoppable, psychological wants are unnecessary and can be halted. The speaker highlights the fundamental difference between humans and animals. An animal's center is nature, and it fulfills its purpose by remaining within natural boundaries. However, a human's true center is the soul or the ultimate truth. While humans share biological needs with animals, they cannot find fulfillment through material consumption alone. Acharya Prashant asserts that for a human, living solely for physical pleasures like food and sex while ignoring the soul is a state of unrighteousness. He notes that humans accumulate material wealth and knowledge only because they have lost touch with their spiritual center. He further explains that true health and beauty are byproducts of living according to one's spiritual nature rather than obsessive physical maintenance. Using the examples of sages like Shri Buddha and Shri Mahavira, he suggests that a life dedicated to righteousness brings a natural radiance to the body. He warns that when the essential need for the soul is ignored, humans develop insatiable hungers for unnecessary things like fame, security, and sensory pleasures. This leads to a state of perpetual restlessness and disease, despite material abundance. Finally, Acharya Prashant discusses the nature of surrender and action. He explains that as one's consciousness grows, one becomes choice-less and moves in harmony with the truth, similar to how a cow grazes or the wind blows. He contrasts desire-driven actions, which are performed to achieve a result, with soul-driven actions, which flow from a state of completeness. Referring to Kabir Saheb, he clarifies that while the soul itself is beyond labels of righteousness or unrighteousness, the mind's duty is to strive toward the soul. True peace is found when one stops living for the unnecessary and aligns with the essential.
