Yoga
Explanation
Ancient Indian philosophy is broadly classified into Astika (Orthodox) and Nastika (Heterodox) schools based on the acceptance of Vedic authority. The Astika tradition comprises six major philosophical systems known as the Shad-Darshanas, which developed during the post-Vedic period.
Analysis of the Options:
- Yoga (Correct): The Yoga school of philosophy was systematized by the sage Patanjali. He compiled the Yoga Sutras, which serve as the foundational text for this system. Yoga focuses on practical discipline, meditation, and the control of the mind and body to achieve liberation (Kaivalya).
- Nyaya: This school is associated with Sage Gautama and is primarily concerned with logic, epistemology, and the methodology of valid knowledge.
- Samkhya: Founded by Sage Kapila, this is considered the oldest school of philosophy. It propounds a dualistic theory involving Purusha (consciousness) and Prakriti (matter).
- Vedanta: Also known as Uttara Mimamsa, this school focuses on the philosophical teachings of the Upanishads and was systematized by Sage Badarayana in the Brahma Sutras.
Key Takeaway:
Sage Patanjali is the compiler of the Yoga Sutras, which is the authoritative text of the Yoga school of philosophy.
