Why does the text emphasize detachment from worldly relationships when discussing devotion to the Guru?

The text emphasizes detachment from worldly relationships because they are depicted as transient and ultimately unhelpful for achieving the spiritual goal. Chapter 45 states that family members like a mother, father, son, or wife, cannot be fully relied upon as companions in the spiritual quest, as their concerns are often tied to worldly matters. For instance, a son may look at wealth he can claim, and a wife may mourn her own status. In contrast, the Guru is presented as the eternal Brahman. By renouncing the transient world and its attachments, a seeker develops the necessary dispassion (Vairagya) to focus solely on the Guru, which is described as the essential means for spiritual progress.
