According to Chapter 14, what makes human birth so special, and how does it contrast with a life lived without spiritual understanding?

Chapter 14 explains that human birth is exceptionally fortunate because it is the only form through which devotion to God and self-realization can be achieved. The text posits that a person who only focuses on food, sleep, fear, and procreation is no different than an "animal without a tail and horns." The greatness of human life lies in its potential to attain the four types of liberation. This chapter also warns that life is transient, like a flash of lightning, and familial relationships are temporary, like pieces of wood floating together in a river before scattering. Therefore, one must use this precious human birth to pursue spiritual goals and make life meaningful.
