What was Sai Baba's meditation practice and what were some of his key personal characteristics mentioned in the Satcharitra?

According to Chapter 44 of the Shri Sai Satcharitra, Sai Baba's primary meditation was the phrase "Allah Malik," meaning "God is King." The text describes him as a being entirely free from desire, pride, greed, or craving. A particularly notable characteristic was his profound peace and kindness, which he extended even to those who might harm him. His presence was so powerful that simply looking at his smiling face could make one forget all worldly sorrows, and even physical sensations like thirst and hunger would vanish in his extraordinary sight (Darshan).
