Based on the teachings in Chapter 49, what is the all-encompassing role that Sai Baba plays in the life of a devotee?

According to Chapter 49, Sai Baba plays a central and all-encompassing role in a devotee's spiritual life. He is described as the 'crest-jewel of all saints' and the ultimate resting place for His followers, serving as the remover of the difficult wanderings of worldly existence. For His devotees, Sai is the exclusive object of meditation and the focus of their worship. The text asserts that Sai is a 'secret treasure' for them and that love for the Guru's feet is their only true wealth. The author personally attests that complete satisfaction is found in the constant repetition of Sai's name, contemplation of His words, and meditation on His form.
