Why are worldly relationships considered unreliable for spiritual progress, and what must a seeker rely on instead?

Chapter 45 argues that worldly relationships, including those with in-laws, sons-in-law, or even a wife, cannot be fully relied upon for achieving one's spiritual goal. The text explains that family members have their own motivations: a mother and father show affection, a son is concerned with his inheritance, and a wife may mourn for her own status. Ultimately, it states that no one is a true companion in the spiritual quest. Therefore, a seeker of liberation must give up hope in others and instead cultivate strong self-confidence. The text advises that upon final reflection, only one's own self remains at the end. A blessed seeker is one who practices discrimination, renounces worldly enjoyments, and girds up their own loins to achieve the spiritual goal.
