According to Chapter 14, what makes human birth so special, and what is the consequence of not living a meaningful life?

Chapter 14 explains that human birth is exceptionally fortunate because it is the only form through which devotion to God can be achieved, leading to liberation and the realization of the Self. If one does not make their life meaningful, their birth is considered a useless burden on the earth. The text elaborates on this point, stating that a person who knows nothing beyond basic survival instincts like food, sleep, fear, and procreation is merely like an animal. This highlights the unique spiritual potential offered by a human life, which should not be wasted.
