How does Chapter 33 suggest one should use Udi for daily purification, and what are its ultimate rewards?

Chapter 33 of the Shri Sai Satcharita outlines a specific daily practice for purification using Udi. It instructs that after one's morning face-washing and bathing, they should apply the Udi. The practice also involves drinking the Udi along with Charanteerth, or holy water from the saint's feet. Following this ritual is said to make a person purified. The chapter goes on to describe the ultimate rewards of this practice, stating that this special quality of Udi, when consumed, will grant a full lifespan, lead to the complete removal of sins, and ensure the devotee experiences happiness and contentment forever.
