What was the nature of Sai Baba's speech, and why did Das Ganu have such strong faith in it?

According to the teachings in chapter 20, Sai Baba's speech was not comprised of mere words but was considered "Brahma-likhit," or divinely ordained. The text emphasizes that not a single letter spoken by Baba would go to waste and would invariably achieve its purpose over time. Das Ganu's firm belief was rooted in this understanding. He knew that Baba's words, whether spoken in jest or seriousness, were never false and always contained profound, hidden meanings, described as "mines of meaning." Das Ganu's faith was so strong that even when Baba gave the seemingly impossible advice that a maidservant would solve his scholarly problem, he accepted it as truth, believing that the Guru's word is a vow to fulfill a devotee's request, as stated in chapter 20.
