How does the text use the analogy of a devoted wife to explain the ideal relationship with a Guru?

Chapter 45 explains that a disciple's devotion to a Guru should be like that of a chaste and devoted wife (Pativrata) to her husband. Just as a devoted wife's heart is steady, her love for her husband is boundless, and he is her only lifelong support, a disciple should have a singular, unwavering focus on the Guru's feet. The text uses this as a powerful metaphor for pure devotion, noting that a devoted wife never considers another man as her husband. However, it also clarifies that the love for a Guru is even greater and has no limits, surpassing the comparison to worldly relationships.
