According to Chapter 14, why is human birth considered so special and what happens if we don't make it meaningful?

Chapter 14 of the Sai Satcharitra 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 cautions that if one does not make life meaningful, their existence is a useless burden. A person who knows nothing beyond basic survival instincts like food, sleep, fear, and procreation is likened to an animal "without a tail and horns." As mentioned in this chapter, this human life offers the unique opportunity for the four types of liberation to fall at one's feet, making it a precious gift that should not be wasted on transient worldly affairs.
