PUBLISHERS' NOTICE
Our original intention, when we arranged for the publication of this book, and, in fact, almost up until it went to press, was that it should be, in a measure, supplementary to our little book, "Science of Breath" by the same author—that is to say, it should take up the subject of "Hatha Yoga" with the exception of that phase of the subject (breathing, etc.) which has been covered in that book. But at the last moment we decided that it would be a mistake to publish a book on "Hatha Yoga" with such an important part of the subject as Yogi Breathing omitted, even though that subject had been covered in another book. To omit that important phase of the subject would be working an injustice to those who purchased the new book, as many of such purchasers would never have read the first book, and would be justified in expecting that the present book would treat of all phases of the general subject. So we decided to incorporate in the present volume those parts of "Science of Breath" which belonged strictly to the subject of "Hatha Yoga," omitting such portions as belonged rather to the other branch of the Yogi Philosophy, i.e., Raja Yoga. We mention these facts that the purchasers of this book, who have also read our former book, might not accuse us of filling a new book with parts of an old one. We advertised this book, intending to give only the supplemental parts, as above stated, and the portions of "Science of Breath," which have been added thereto, have been inserted at our own expense, and in the nature of "good measure," or the "baker's dozen."
