Background Information: The Publisher, The Yogi Publication Society is a press started by William Walker Atkinson at the turn of the 20tdh century to promote his writings on "New Thought," which was the New Age movement of the time. Atkinson himself was quite a character. He was a prolific writer, with over 150 books to his credit, often under any of several pen names. He rose to prominence at the beginning of the 20th century, but seems to have become forgotten in the following decades, though he and the Yogi Publication books are experiencing a new renaissance at the beginning of the 21 century. Many of the books were written by Atkinson, but they also published other prominent metaphysical works by other authors. The company has changed hands a number of times, so many that the original history was lost to the current owners, but the books are still in print, and still inspiring spiritual seekers. The author of this book, Yogi Ramacharaka, was one of William Walker Atkinson's many pen names. This little book (88 pages) is a classic! Despite being over 100 years old, the breathing exercises it offers are easy to practice and very practical. Beginning at the beginning, it thoroughly discusses the western concept of breath and the Eastern concept and why they're important. Of course there's a discussion of Prana, the Hindu word for the metaphysical energy (AKA Chi, or Ki) that is cultivated both through breath and also through meditation, All these chapters are concise and short and they're followed by both basic and additional exercises. Specifically, you'll discover the Complete Yogi Breath, The Seven Yogi Developing Exercises, Seven Minor Yogi Exercises, Vibrational Breathing, and some other things you can practice as well. There are techniques to use breath and imagery to empower your meditation, health and visualization. No New Thought book would be complete without some psychic phenomena exercises and this book includes those as well, so if you want some basic practiced in Thought Projection, Psychic Healing, Charging your Aura and discovering your higher self, that's included too. Breathing practice is often taught as part of Yoga or Meditation teaching, but it can be practiced all by itself to improve your health and concentration. The book is over 100 years old, so it's no longer protected by copyright. As such, there are a lot of versions available published by a lot of different sources, from the blue hardcover published by Yogi Publication Society, to various paperback versions and even downloadable PDFs that can be found on line. It's well worth a read, and a practical addition to anyone's metaphysical or physical culture book collection.
