I'm trying to understand how to identify a true Sadguru. What signs and characteristics does Chapter 48 of the Sai Satcharitra suggest I look for?

According to the guidance found in Chapter 48 of the Sai Satcharitra, identifying a true Sadguru involves looking beyond superficial qualities. You should seek one who possesses not just knowledge, but direct, full self-experience. A key sign is profound humility; a Sadguru is free from pride in their scholarship and does not maintain an ego of being superior to the disciple. Look for a benefactor who treats the "small and the great as equals" and has fatherly love for their followers. Their defining attitude, as this chapter reveals, is one of self-sacrifice for the disciple's sake, rather than expecting service. The place of a Sadguru is described as a "storehouse of supreme peace."
