The Yoga Sutras consist of 196 (or sometimes 195, depending on the version) short, aphoristic verses called "sutras" (which means "thread").

The Yoga Sutras are often considered a guide for Raja Yoga (Royal Yoga), emphasizing mental discipline and meditation, as distinguished from other forms like Hatha Yoga (which focuses more on physical postures). Many modern yoga styles draw inspiration and philosophy directly from Patanjali's teachings
