Patanjali

The author of the Yoga Sutras. Patanjali lived sometime between about 200 B.C.E. and 200 C.E., but the exact date is unknown. Patanjali traveled throughout much of India, studying and analyzing what different practitioners and teachers were doing under the name of "yoga." Patanjali probably did not actually contribute any new ideas or practices to yoga, rather he provided a valuable structural analysis of the yoga of his day.
