Based on the teachings in Chapter 12, why do saints like Sai Baba incarnate, and how do they interact with their devotees?

According to Chapter 12, a great soul like Sai incarnated for the sake of His devotees. The text beautifully illustrates that saints are so drawn by the love of their devotees that they are willing to spend their millions of merits for them. They do not see any obstacles, like mountains or cliffs, as hindrances when it comes to helping a devotee. This chapter emphasizes the saint's role as a guide and protector, comparing them to the sun that dispels the darkness of ignorance and the mythical sage Agastya who drank the ocean of worldly existence, showing they exist to help followers navigate life's challenges.
