What was the nature of Sai Baba's spiritual practice or meditation according to the Satcharitra?

According to Chapter 44 of the Shri Sai Satcharitra, Sai Baba's primary meditation was the simple yet profound utterance "Allah Malik" (God is King). His spiritual practice was deeply integrated into his being, characterized by a state of desirelessness and freedom from pride, greed, or craving. The text highlights that his greatness was evident in his immense peace and his kindness even towards those who wished him harm. This indicates his path was one of continuous God-remembrance and internal purity, rather than a specific, named yogic discipline. His smiling face alone was enough to make devotees forget worldly sorrows.
