According to the summary of Das Ganu's song, how are Sai Baba's divine nature and universal appeal described?

The summary of Das Ganu's song in Chapter 4 provides a rich description of Sai Baba's multifaceted divine nature and his universal appeal. The song portrays Baba's power as a boat to help devotees cross the worldly ocean and references the miracle of the Ganga-Yamuna flowing from His toes. It powerfully identifies Him with the Hindu Trinity, stating He speaks like Brahma, can show a fierce form like Rudra (Shiva), and is sometimes playful like Krishna. The song also highlights his role as a unifier; though He loves Hindus, He lives in a mosque to be accessible to Muslims. He embodies contrasts, being a beggar who shames the wealthy. This inspired song encapsulates Baba's unfathomable power, his strange and wonderful Leelas, and his ability to be everything to all his devotees.
