"Chi" is how we represent the Chinese pronounciation, "Ki" is the Japanese. Joriki is the chi - or ki - that we generate ourselves through our actions, our diet, our attitude and, especially, our daily practice. Tariki is "other chi" that we soak up from being around people, places and situations. One reason we (usually) feel so good after class is because of the Joriki of our beautiful, well-meaning, sincere and devoted friends in class. It is important for each of us, and for our collective efforts, not to make a habit of coming to class depleted and expecting to be filled up with Tariki. Rather, learn to take responsibility for contributing by coming ready with a reserve of Joriki, so you are ready for anything . . .
