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

According to Chapter 33 of the Shri Sai Satcharita, the glory of Sai Baba's Udi is immense and it is even referred to as the ornament of Shankara (Shiva). For those who approach its use with genuine feeling and faith, the text promises the immediate removal of obstacles. A daily practice is also suggested for purification: after bathing, one should apply the Udi and drink it with Charanteerth (holy water). Chapter 33 further elaborates that consuming the Udi can grant a full lifespan, lead to the complete removal of sins, and bestow everlasting happiness and contentment upon the devotee.
