The Yoga Sutras of Patanjali is widely regarded as the most authoritative text on yoga. It comprises a collection of 196 Indian sutras ("threads" - as sutra translates from Sanskrit) written 1,700 years ago. These threads or aphorisms were compiled by the Indian sage Patanjali and offer guidelines for living a meaningful and purposeful life.The book is organized into four parts and provides descriptions of the eight limbs of yoga, such as pranayama and asana. The translated text is presented alongside a clear and insightful commentary by Swami Vivekananda, which makes them more accessible to the modern reader and yoga practitioner. His message of universal brotherhood and self-awakening remains relevant today, especially in the current backdrop of widespread political turmoil around the world.
