What is the main message about the Sadguru and devotion conveyed in Chapter 49?

The central theme of Chapter 49 is the supreme and inexpressible nature of the Sadguru, Sai Baba, and the path of devotion to Him. It establishes that Sai is the "crest-jewel of all saints" and the ultimate refuge for devotees. The chapter emphasizes that true wealth is not material but is the "love for the Guru's feet." A key message, as stated in Chapter 49, is the hierarchy of spiritual practices, which concludes that "the meditation on one's own Guru is the greatest of all," surpassing pilgrimages, vows, and even the singing of God's name. It defines a true devotee as one who is entirely free from ego.
