I gathered from the internet page that the first part was of someone's experience at a spa where he was on a Water Fast and bed rest? and the second part was the actual Master-Cleanse book written by burroughs? But I don't have the book in print, so can't say.
I think as they said in the other thread, an enema washes the lower colon area while a SWF (Salt-Water-Flush) washes the whole intestinal tract start to finish. But, you may not be so toxic so you can just do enemas? Everybody's different. :) I definitely think you should try it, especially if you're not getting enough rest. Happy cleansing! :)
