[नतं स्याज्जानुनमनात् क्षिप्तं विक्षेपणाद् बहि] । उद्वाहितं च विज्ञेयमूर्ध्वमूद्वाहनादपि । प्रतीपनयनं यत्तु परिवृत्तं तदुच्यते ॥ २६२॥

sanskrit

Nata (bent) results from the bending of the knee. Kṣipta (thrown out) is due to flinging the shank outward. Udvāhita (raised) is to be understood from the upward lifting of the shank. Parivṛtta (turned back) is so called when the leg is drawn back in the opposite direction.
