What is the specific daily ritual for using Udi for purification mentioned in the Satcharita?

Chapter 33 of the Shri Sai Satcharita outlines a specific daily practice for using Udi to achieve purification. The text advises that after completing one's morning routine of face-washing and bathing, one should apply the Udi. In addition to external application, the chapter mentions the practice of drinking the Udi along with Charanteerth, which is holy water consecrated by the feet of a saint. Following this daily ritual is said to lead to the user becoming purified. This highlights a prescribed method for incorporating Udi into one's daily devotional practice for spiritual benefit.
