Raja Yoga: Including Patanjali's Yoga Aphorisms

The subject of this book is the form of Yoga known as Raja-Yoga. The aphorisms of Patanjali are the highest authority on Raja-Yoga, and form its textbook. The other philosophers, though occasionally differing from Patanjali in some philosophical points, have, as a rule, acceded to his method of practice a decided consent. The first part of this book comprises several lectures to classes delivered by the writer in New York. The second part is a rather free translation of the aphorisms (Sutras) of Patanjali, with a running commentary.
