Can you explain the supreme importance and rewards of devotion to the Guru as outlined in Chapter 46?

Chapter 46 of the Sai Satcharitra elevates loving devotion to the Guru to the highest spiritual practice, even calling it 'Dharma'. It promises immense rewards for those who practice it with heart and soul, stating that Peace, Detachment, and Fame will always remain under their control. The text makes a powerful claim that a true devotee of the Guru will lack nothing and can obtain whatever they desire in their heart without effort. In a striking comparison, the chapter mentions that even the state of Brahman-realization serves such a devotee like a maid-servant, and liberation is not something they even need to ask for.
