And btw, David Murphy puts out some good info about the UT. I just watched his video on the Human body workshop, very good. (nothing wrong with giving him some support)
Also google Shivambu Gita. It is published on this site.
The toughest part of UT for me is the dèep seated social/cultural conditioning against urine, and how pervasive the lies from the establishment medical proffessional have shaped out minds to believe that urine is waste product and should not be used.
Bear that in mind when talking to your friends, familly, or regular doctor.
The cultural conditioning is very very strong.
