How does Chapter 33 suggest one should use Udi for spiritual benefits?

According to Chapter 33, for spiritual purification and benefits, a devotee should use Udi on a daily basis. The process described involves applying the Udi after completing one's morning face-washing and bathing. In addition to external application, the text recommends consuming it by "drinking along with Charanteerth (holy water from feet)." Following this practice is said to lead to purification. The chapter also emphasizes that approaching the Udi with "feeling and faith" is key to experiencing its power, such as the immediate removal of obstacles.
