What is the significance of Sai Baba's Udi, particularly in providing relief from troubles and as a form of blessing?

The significance of Sai Baba's Udi, or sacred ash, is multifaceted, acting as both a potent remedy and a divine blessing. As detailed in Chapter 35, it holds immense power to alleviate suffering. For instance, a gentleman from Bandra who was tormented by his deceased father in his dreams and could not sleep found immediate relief. A Sai devotee advised him to apply the Udi to his head and keep it under his pillow while remembering Sai. This simple act completely erased his bad dreams and restored his sleep. This story illustrates the Udi's 'natural tendency' to remove trouble. Furthermore, the Udi is a form of 'Prasad' and blessing. Chapter 35 also clarifies that receiving the Udi along with a blessing from Baba signifies his permission to depart, underscoring its role as a tangible sign of his grace and consent.
