Who does the text use as an analogy for the ideal disciple's love for their Guru?

The text in Chapter 45 uses the example of a chaste and devoted wife, or Pativrata, to illustrate the kind of singular love a disciple should have for their Guru. A Pativrata's love for her husband is described as boundless, and he is her only lifelong support; she never considers another man in his place. In the same way, a disciple should feel this singular, unwavering love toward the Guru's feet. However, Chapter 45 also clarifies that while this is a useful metaphor, the love for a Guru is even greater and has no limits, a truth which a true disciple understands.
