Can you explain the analogy of the 'devoted wife' used to describe a disciple's relationship with their Guru?

Chapter 45 uses the powerful metaphor of a devoted and chaste wife (Pativrata) to illustrate the ideal disciple's love for their Guru. Just as a devoted wife respects other family members but holds a singular, boundless love only for her husband, a disciple should have an exclusive focus on the Guru's feet. The text explains that her heart never leaves her home, and her husband is her only lifelong support. In the same way, a disciple's devotion should be unwavering and singularly directed towards the Guru. However, Chapter 45 also notes that while this is a useful metaphor, the love for a Guru actually has no limits, a greatness a true disciple comes to know.
