According to the provided text, how did Sai Baba communicate his advice and why was it often considered incomprehensible?

Sai Baba's method of giving advice was varied and often enigmatic, which made it difficult for many to comprehend fully. As detailed in Chapter 22, He employed many different approaches. Sometimes His words were filled with 'hidden meanings' or He would 'leave ambiguity and walk away in anger.' At other times, He would communicate through humor and jokes, or be 'openly decisive.' His deeds were described as 'incomprehensible' and 'unimagined.' The text emphasizes this by stating that his miracles were as impossible to measure as trying to count raindrops. This unpredictable and multi-layered communication style was part of his unique way of guiding devotees, often revealing its true meaning only when the time was right.
