How does the text illustrate the supreme purifying power of saints, even when compared to sacred rivers?

Chapter 10 provides a powerful illustration of the purifying power of saints. It explains that even the most sacred rivers, such as the Ganga, Godavari, and Kaveri, which wash away the sins of the world, themselves desire the feet of saints. This is because these holy rivers cannot remove their own accumulated sins without attaining the feet of a saint. This metaphor highlights that the company of saints is the ultimate purifier, possessing a power that transcends even that of nature's most sacred elements. It is the only means to attain the best state and find true rest.
