The Yoga Sutras of Patanjali is a key text in yoga philosophy, offering a comprehensive guide to mental discipline and spiritual growth. Comprising 196 sutras in four chapters, it outlines the nature of the mind and introduces yoga as the practice of quieting mental fluctuations. The text details the eightfold path (ashtanga yoga), which includes ethical guidelines, postures, breath control, and meditation, all aimed at achieving samadhi (deep meditative absorption) and kaivalya (liberation). It also discusses the supernatural powers that may arise through practice, emphasizing that the ultimate goal is spiritual freedom and self-realization, beyond worldly distractions.
