Can you summarize the main themes and the author's feelings as expressed in Chapter 49 of the Sai Satcharitra?

Chapter 49 of the Sai Satcharitra is a devotional reflection on the greatness of Sadguru Sai Baba. The author expresses that language is inadequate to praise the Guru, stating that even the Vedas grew weary in their attempts. As detailed in this chapter, the author feels compelled to write about Sai's qualities, comparing the process to arranging a feast of bliss to be shared. A central theme is the necessity of humility and ego-surrender for a devotee. The text asserts that someone with pride in their body or knowledge cannot be a true devotee, and that the greatest spiritual practice, surpassing even pilgrimages or sacrifices, is the meditation on one's Guru.
