How does Chapter 45 explain the ideal devotion of a disciple using the analogy of a devoted wife?

Chapter 45 uses the metaphor of a chaste and devoted wife, or "Pativrata," to illustrate the ideal relationship between a disciple and their Guru. Just as a devoted wife's love for her husband is singular and boundless, and he is her only lifelong support, a disciple should feel the same singular love toward the Guru's feet. The text clarifies that while this is a useful comparison, the love for a Guru actually has no limits and its greatness is known only to a true disciple. This singular focus means that, like a devoted wife who never thinks of another man as her husband, the disciple's mind should be fixed solely on the Guru.
