"When doing your training under a tree in the forest or out in the open, you
will not find a privy already built. So, using water from some convenient valley
stream or river, clean yourself off with sand. Since you do not have any ashes at
this time to cleanse yourself with, simply use two sets of seven balls of sandy soil.
The way to use these fourteen balls is as follows: after having removed your robe,
folded it, and put it aside, you take soil that is sandy [rather than dark earth], shape
it into balls about the size of a large soybean, and place these atop a stone or some
other convenient place, with two rows of seven balls each. Then, provide yourself
with some pebbles that can be used for scouring your hands. After that, you relieve
yourself. After you have finished relieving yourself, use a wooden or bamboo toilet
spatula, or some paper, to clean yourself off. You then go to the edge of the water
to wash. Make sure to take three of the balls with you to clean yourself. Put one of
the balls in the palm of your hand, add just a little water, mix the ingredients
together until their consistency is thinner than mud and quite soupy, and begin by
cleaning off your genitals. Then take another sand ball and, preparing it as before,
clean off your buttocks. Again, prepare a sand ball as before and, in the same
manner, clean off your hands."
