The Yoga-System of Patañjali - Or the Ancient Hindu Doctrine of Concentration of Mind, Embracing the Mnemonic Rules, Called Yoga-Sutras, of Patanjali and the Comment, Called Yogabhashya #220130

My deepest insight into this system and into what little I know of the philosophy of India I owe to Professor Hermann Jacobi of Bonn. Each visit to the little city on the Rhine adds to my debt of gratitude to him and reveals to me the beauty of the Scholar's life. On my return from each visit to India I laid the work in its several Stages before Professor Lanman, my teacher in my student days and now my colleague. To him I owe the revision of the manuscript for the press and a comparison Of most of the translation, either in manuscript or in proof, with the original. His rigorous criticism has detected many over sights which strike a fresh pair Of eyes more quickly than those of the author. For his ready and ungrudging help through many years of intimate friendship my hearty thanks.
