How is Sai Baba's multifaceted divine nature described in Das Ganu's song?

A summary of Das Ganu's inspired song in Chapter 4 portrays Sai Baba as a manifestation of the divine in many forms. The song describes Baba as the embodiment of the Hindu Trinity—Brahma, Vishnu, and Shiva. It explains that he speaks with the creative wisdom of Brahma, can show a fierce, protective form like Rudra (Shiva), and at times displays a playful nature like Krishna. The song highlights his unique role in uniting different faiths, noting how he, a Hindu-revered saint, lived in a mosque for the sake of Muslims. He is depicted as a paradox: a beggar who shames the wealthy and a holy man whose mosque contains a sacred fire (Dhuni) that produces Udi, a holy ash for devotees. This description captures his unfathomable power and all-encompassing spiritual presence.
