What were the different terms used for the sacred ash, and what was the significance of the song Baba sang about it?

The sacred ash from Baba's Dhuni is referred to by three different words that hold the same meaning: Ash, Vibhuti, and Udi. The significance of this Udi is further highlighted by a song Baba was heard singing when he was absorbed in love. Chapter 33 records a fragment of this song: 'Ramate Rama Ayoji Ayoji, Udiyan ki Goniyan Layoji,' meaning 'Rama rejoices, O mother, bringing bags of Udi.' When his mind became playful and joyful, he would sweetly sing this refrain repeatedly. This indicates the supremely auspicious nature of the Udi and its boundless availability, as the Dhuni produced 'countless bags of Udi' for the benefit of all.
