The text uses the metaphor of a 'chaste and devoted wife.' How does this comparison illuminate the nature of the Guru-disciple relationship and its superiority over worldly bonds?

The text uses the metaphor of a chaste wife (Pativrata) to illustrate the singular and unwavering love a disciple should feel toward their Guru's feet. Just as a devoted wife considers her husband her only lifelong support and never thinks of another, a disciple should have singular love for their Guru. Chapter 45 elaborates that this love for the Guru is actually even greater and without limits. This bond is contrasted with worldly relationships—like those with a mother, father, son, or wife—which are ultimately unreliable for achieving the spiritual goal, as no one is a true companion on the spiritual path.
