How does the text describe the ideal devotion a disciple should have for their Guru, and what analogy is used to explain it?

Chapter 45 explains that a disciple's devotion to their Guru should be singular and unwavering, much like the love a chaste and devoted wife (Pativrata) has for her husband. The text describes how this type of wife respects others, like her in-laws, but her heart's steadfast love is reserved only for her husband, who is her lifelong support. In the same way, a disciple should feel this singular love toward the Guru's feet, seeing the Guru as their ultimate spiritual support. However, the chapter also notes that while this is a useful metaphor, the love for a Guru is actually limitless and its greatness is known only to a true disciple.
