I appreciate the link, but I really don't understand the mechanics of using a bowl (tabo) without toilet paper or such. Get your hand wet in the tabo, make a first pass at cleaning. Then what? Your hand is dirty, and if you rinse it in the tabo, that water is tainted for all future passes. Considering the first pass is probably the worst, I don't think this is negligible.

I had a friend who would bring a cup of water to the bathroom, barely dip the toilet paper in water, and use the wet paper to get cleaner. But without having (and disposing of the) paper after each pass, I don't see how it would work.

Thank you for this.
