Fasting, or, soo-ney-wen, is purification on all levels, including the physical. It is the act of giving up what is precious to you so that others can have it. It teaches you to appreciate the basic nourishment in life so that you don't abuse it. Fasting also sensitizes the body to nonphysical vibrations, and to one's own inner workings.
— Evan T. Pritchard, No Word for Time
