Based on the summary of Das Ganu's song, how is Sai Baba's multifaceted and universal nature described?

Das Ganu's inspired song, as summarized in Chapter 4, portrays Sai Baba's universal and multifaceted divine nature. He is depicted as the Hindu Trinity in one form—Brahma, Vishnu, and Shiva—who sometimes speaks with the wisdom of Brahma, shows a fierce form like Rudra, or is playful like Krishna. His universality is highlighted by his ability to bridge religious divides, loving the Hindus while residing in a mosque for the Muslims. The song also describes his paradoxical nature as a 'beggar' who 'shames the wealthy' with his spiritual richness, and mentions his mosque's sacred Dhuni fire, from which he gives Udi to devotees.
