How does the scripture describe the ideal devotion of a disciple to their Guru using an analogy?

The scripture uses the powerful metaphor of a chaste and devoted wife (Pativrata) to illustrate the ideal bond between a disciple and their Guru. As explained in Chapter 45, just as a devoted wife respects her in-laws and other family members but keeps her heart singularly focused on her husband, a disciple should feel a similar singular love toward the Guru's feet. Her love for her husband is boundless, and he is her only lifelong support. The text clarifies that while this is a useful metaphor, the love for a Guru is even more limitless. This singular focus, detached from worldly distractions, is presented as the model for a true Sai-devotee.
