YOGA IS RESTRAINING THE MIND-STUFF FROM TAKING VARIOUS FORMS. Patanjalis Yoga Sutras, written almost two millennia ago, is a comprehensive text on the theory and practice of yoga. From concentration, its spiritual uses and practice, to manifestation and the process of attaining liberation, the aphorisms state the path to self-realization. One of the key texts of classical yoga, this edition of Patanjalis Yoga Sutras is a translation by Swami Vivekananda. It includes the Sanskrit text, its transliteration, and translation followed by an in-depth commentary of each sutra.
