If the body is so impure and life is so fleeting, what is the practical advice for how to live my life day-to-day?

Chapter 8 provides clear, practical guidance on this matter. Despite describing the body as an impure and foul "skeleton of bone and skin," it is also the essential tool for spiritual liberation. The advice is to treat the body as a servant, not the master. You should provide it with food and clothing for sustenance but avoid pampering it, as this can make it a "doorway to hell." The primary purpose of maintaining the body is to apply it "toward spiritual progress to avoid birth and death." As Chapter 8 further elaborates, one should recognize that all worldly things are perishable and focus on what brings eternal benefit, which is the worship of God and engaging in holy stories, rather than wasting this precious human life.
