What are the general benefits and spiritual significance of using Sai Baba's Udi according to the Satcharita?

According to Chapter 33 of the Shri Sai Satcharita, the glory of Sai Baba's Udi is immense. It is described as the "ornament of Shankara (Shiva)," and discussing it with faith and feeling can lead to the immediate removal of obstacles. The text outlines several key benefits for those who use it daily after bathing: it purifies the individual, especially when consumed with Charanteerth (holy water from feet). Furthermore, the book highlights a special quality of Udi, stating that consuming it can grant a full lifespan, ensure sins are completely removed, and bring about lasting happiness and contentment. This illustrates that its power extends beyond physical healing to profound spiritual purification and well-being.
