According to Hemadpant, what is the spiritual significance of Udi and what is the proper way to use it?

In Chapter 33, Hemadpant elevates Udi to a high spiritual status, calling it an "ornament of Shankara (Shiva)" and asserting that discussing its glory with faith removes obstacles immediately. He outlines a daily ritual for its use: after one's morning face-washing and bathing, one should apply the Udi. He also mentions drinking it along with Charanteerth (holy water from a Guru's feet) to achieve purification. Beyond the ritual, Hemadpant describes its special qualities, stating that consuming Udi ensures a full lifespan, complete removal of sins, and the attainment of everlasting happiness and contentment.
