Based on the text, what were some of Sai Baba's spiritual practices and expressions of devotion?

Chapter 5 provides insight into several of Sai Baba's spiritual practices. He maintained a sacred fire, or dhuni, into which he symbolically offered his ego, desires, and worldly inclinations as oblations. While seated, he would constantly have the words "Allah-Malik" (God is the Master) on his tongue. Before living in the mosque, while at the Takia, his devotion took a different form; he would dance beautifully and sing sweetly with love, tying bells to his feet and playing a small tambourine. Furthermore, his great love for lighting lamps for the festival of lights was another profound expression of his devotion, which ultimately led to the miracle of turning water into fuel for the lamps.
