ABSTRACT
Yoga is of immemorial antiquity. There are many books about it, ancient and modern. The acknowledged masterpiece of this literature is The Yoga Sûtras of Patanjali. The Yoga Sûtras are divided into four sections or books. The first and second of these deal with the "right withdrawal" of the spiritual man from the veils and meshes of his psychic nature—the overcoming of mental habits and emotional moods. The third book is concerned with the "spiritual powers", such powers being the natural mode of functioning of the spiritual man. The fourth book deals with the workings of that law the application of which to the individual brings the spiritual man to germination, growth, and flowering, from his material seed or sheath. Yoga is the complete cessation of the activity of the versatile psychic nature. The first two means of Yoga are disciplinary and initiatory; they give the moral strength and resilience.
