Beyond specific remedies, what is the role of Udi Prasad in the broader context of receiving Sai Baba's darshan and blessing?

In the broader context described in Chapter 35, receiving Udi Prasad is the culmination of a visit to Sai Baba, acting as both a physical blessing and a procedural necessity. The text explains that after Baba gives his darshan, devotees would receive the "Udi Prasad and take his blessing" before returning home, filled with faith. This act also serves as Baba's explicit permission to leave, as the chapter makes clear that no one could depart without his consent. The blessing along with the Udi is the permission to leave. Thus, the Udi is a tangible symbol of his grace, a confirmation of his blessing, and the sanctioned approval for a devotee's departure from Shirdi.
