What are the general benefits of using Sai Baba's Udi as described in the Satcharita?

According to Chapter 33 of the Shri Sai Satcharita, the glory of Baba's Udi is immense and multifaceted. The sacred ash is described as an ornament of Shankara (Shiva), and discussing its virtues with faith can lead to the immediate removal of obstacles. The text states that regularly applying Udi after bathing and drinking it with holy water purifies a person. Furthermore, consuming Udi is said to grant a full lifespan, completely remove sins, and bestow everlasting happiness and contentment upon the devotee. These profound benefits are highlighted by Hemadpant as part of the feast of sweet story-nectar provided by Sai.
