What metaphor is used to describe the ideal relationship between a Guru and a disciple, and what does it signify?

Chapter 45 employs the powerful metaphor of a devoted and chaste wife's (Pativrata) relationship with her husband to illustrate the ideal bond between a disciple and their Guru. This metaphor signifies singular, unwavering love and focus. The text explains that while a devoted wife respectfully acknowledges others, her heart never leaves her home, and her love for her husband is boundless. Similarly, a disciple is encouraged to have this kind of singular love for the Guru's feet. However, the chapter also clarifies that the love for a Guru is without limits and its greatness is something a true disciple comes to know, suggesting it even transcends this powerful comparison.
