Descrizione
From author's "The subject of the present book is that form of yoga known as Raja-yoga. The aphorisms of Patanjali are the highest authority on Raja-yoga and form its textbook. ... The first part of this book comprises several lectures delivered by the present writer to his classes in New York. The second part is a rather free translation of the Aphorisms (Sutras)of Patanjali, with a running commentary."
