A flower is not better when it blooms than when it is merely a bud, pronounces tennis pro Gallwey, current cult-figure, public television star, and author of The Inner Game of Tennis, which started all the brouhaha about him in the first place. This is volume two, and though nothing new has happened to the inner game (self one and self two are still fighting it out in the unconscious battle for the perfect forehand), this new effort is likely to sell at least as many copies as did volume one. And that's over 140,000. If you believe what Gallwey tells you, focusing your concentration on the seams of the tennis ball (all of this, naturally, can be applied to the rest of life as well) is sufficient to distract Self One--your conscious self--and keep it occupied while Self Two--the unconscious self that knows more about tennis than Self One does--hits the ball. Once you know that, however, you know the whole Zen megillah, and both selves one and two can nod off instead of plowing through this box-office bore.
