Samkhya Karika 68

प्राप्ते शरीरभेदे चरितार्थत्वात् प्रधानविनिवृत्तौ ।
ऐकान्तिकमात्यन्तिकमुभयं कैवल्यमाप्नोति ॥ ६८ ॥

prāpte śarīrabhede caritārthatvāt pradhānavinivṛttau ।
aikāntikamātyantikamubhayaṁ kaivalyamāpnoti ॥ 68 ॥

prāpte=on attaining; śarīrabhede=on attaining separation from the body; caritārthatvāt=its purpose having been served; pradhāna=mūla Prakriti; vinivṛttau=having ceased to act; aikāntikam=absolute; ātyantikam=final; ubhayaṁ=both; kaivalyam=freedom; āpnoti=attains

When, in due course, Prakriti has ceased to act, Purusha, having attained separation from the body, its purpose having been fulfilled, attains final and absolute liberation.
