How does the author use the metaphor of a chaste wife to illustrate the ideal love a disciple should have for their Guru?

In Chapter 45, the author employs the metaphor of a chaste and devoted wife (Pativrata) to explain the nature of a disciple's love for their Guru. A devoted wife's heart is steady and never leaves her home; her love for her husband is singular, boundless, and he is her sole lifelong support. She never even considers another man in that role. In the same way, the text explains, a disciple should feel an exclusive and all-encompassing love toward the Guru's feet. However, the author also notes that while this is a useful metaphor, the love for a Guru ultimately has no limits, and a true disciple understands its profound greatness beyond any worldly comparison.
