What is the 'Vag-yagna' or 'speech-sacrifice' mentioned in Chapter 45, and what is the role of the listener in it?

The 'Vag-yagna' or 'speech-sacrifice' mentioned in Chapter 45 refers to the creation and narration of the Shri Sai Satcharitra itself. The author, presenting himself as someone of little knowledge, humbly asks the wise listeners to accept this offering with a grateful heart. The role of the listener is crucial for the completion of this sacred act. As detailed in Chapter 45, one who listens to these stories with a concentrated mind while bowing at Sai's feet is performing a greatly auspicious and supremely holy act, thereby participating in and completing the speech-sacrifice that the Guru initiated.
