If this seems incredible, let us remember how old whist players note and remember every card in the pack, and can tell whether they have been played or not, and all the circumstances attending upon them. The same is true of chess players, who observe every move and can relate the whole game in detail long after it has been played. And remember, also, how one woman may pass another woman on the street, and without seeming to give her more than a careless glance, may be able to relate in detail every feature of the other woman's apparel, including its color, texture, style of fashioning, probable price of the material, etc., etc. And a mere man would have noticed scarcely anything about it--because he would not have given it any attention. But how soon would that man learn to equal his sister in attention and observation of women's wearing apparel, if his business success depended upon it, or if his speculative instinct was called into play by a wager with some friend as to who could remember the most about a woman's clothing, seen in a passing glance? You see it is all a matter of Interest and Attention. But we forget that the Attention may be developed and cultivated, and we complain that we "cannot remember things," or that we do not seem to be able to "take notice." A little practice will do wonders in this direction. Now, while the above exercises will develop your memory and powers of observation, still that is not the main reason that we have given them to you. We have an ulterior object, that will appear in time. We aim to develop your Will-power, and we know that Attention stands at the gate of Will-power. In order to be able to use your Will, you must be able to focus the Attention forcibly and distinctly. And these childish exercises will help you to develop the mental muscles of the Attention. If you could but realize the childish games the young Yogi students are required to play, in order to develop the mental faculties, you would change your minds about the Yogi Adepts whom you have been thinking about as mere dreamers, far removed from the practical. These men, and their students, are intensely practical. They have gained the mastery of the Mind, and its faculties, and are able to use them as sharp edged tools, while the untrained man finds that he has but a dull, unsharpened blade that will do nothing but hack and hew roughly, instead of being able to produce the finished product. The Yogi believes in giving the "I" good tools with which to work, and he spends much time in tempering and sharpening these tools. Oh, no, the Yogi are not idle dreamers. Their grasp of "practical things" would surprise many a practical, matter-of-fact Western business man, if he could but observe it.
