http://www.universal-tao.com/article/urine_therapy.html

The author of this short treatise, Coen van der Croon, has become one
of the world's best activists of this ancient and sacred therapy,
mentioned thousands of times in hundreds of world sciptures. Indeed,
the Tantric form of this therapy (the inside of the cup) is the common
bond between the world's religions, which are otherwise quite
different (the outside of the cup) and at odds with each other. Jai
