How should a devotee properly use Sai Baba's Udi on a daily basis for purification and other benefits?

According to the guidance provided in Chapter 33 of the Sai Satcharita, there is a specific daily ritual for using Udi to attain purification. The text advises that after completing one's morning face-washing and bathing, a devotee should apply the Udi. It also mentions drinking the Udi along with Charanteerth, or holy water. Following this practice is said to lead to purification, the complete removal of sins, the blessing of a full lifespan, and the attainment of lasting happiness and contentment. The chapter emphasizes that discussing Udi with faith and feeling also results in the immediate removal of obstacles.
