How is the devotion of a chaste wife used as a metaphor for the Guru-disciple relationship?

According to the teachings in Chapter 45, the singular and boundless love a devoted wife (Pativrata) has for her husband is used as an analogy for the ideal relationship between a disciple and their Guru. Just as a chaste wife's heart never leaves her home and her husband is her only lifelong support, a disciple should feel the same singular love toward the Guru's feet. The text in Chapter 45 explains that while a wife respects others like her father-in-law or brother, her steady heart is devoted only to her husband. Similarly, a disciple's love for the Guru should be exclusive and limitless, forming the foundation of their spiritual path.
