What are the tangible and intangible benefits of having devotion to the Guru as described in Chapter 46?

Chapter 46 of the Sai Satcharitra elaborates on the vast rewards of devotion. For those with worldly desires, it fulfills their wishes. For the desireless, it grants the home of self-bliss. The text asserts that through devotion, one's sins are destroyed and negative tendencies vanish. On a higher level, it is stated that one who possesses such devotion to the Guru will lack nothing and will obtain whatever they desire in their heart without effort. The chapter even claims that the state of Brahman-realization serves such a devotee like a maid-servant.
