Patañjali, believed to have lived between the second and fifth century BCE, is recognized for his works on yoga, grammar, and medicine, with the Yoga Sūtras being his most notable contribution outlining the art and science of yoga meditation. The text consists of four chapters, detailing various practices that lead to self-realization and liberation, while promoting physical, mental, and spiritual disciplines. Despite his contributions, debates persist regarding his true identity and whether a single author produced all significant texts attributed to him.
