In Chapter 45, the author refers to the Satcharitra as a 'Vag-yagna' or 'speech-sacrifice'. What is the significance of this characterization?

By characterizing the book as a "Vag-yagna" or speech-sacrifice in Chapter 45, the author conveys a deep sense of humility and sacred purpose. A yagna is a holy ritual or offering, so calling the book a speech-sacrifice implies that the act of writing and sharing these stories is a sacred offering to the Guru and the devotees. The chapter notes that this auspicious speech-sacrifice was initiated by the Guru and is being completed by putting an "ignorant one" like the author forward. It positions the text not as a mere biography, but as a holy, living instrument for remembrance and attaining peace, especially since Sai's physical form has vanished.
