What is the central theme of Chapter 49 of the Sai Satcharita regarding the Sadguru and the nature of devotion?

Chapter 49 focuses on the inexpressible and unfathomable greatness of the Sadguru, Sai Baba. The author states that even the Vedas grew weary of praising Him and that true praise is silence. However, the bliss derived from Sai's qualities makes it impossible to remain quiet. This chapter presents Sai as the ultimate resting place for devotees and the remover of worldly troubles. It strongly emphasizes that love for the Guru's feet is the only true wealth and that meditation on one's Guru is the greatest of all spiritual practices, surpassing pilgrimages, sacrifices, and even singing Hari's name.
