Canonical Ref: YS 4.34
Sanskrit (Devanāgarī)
पुरुषार्थशून्यानां गुणानां प्रतिप्रसवः कैवल्यं स्वरूपप्रतिष्ठा वा चितिशक्तिरिति
English Scholarly Translation
The dissolution of the guṇas, which are devoid of purpose for the puruṣa, is known as kaivalya, or the establishment in ones own essential nature, or the power of consciousness itself
व्याख्या / Traditional Commentary & Notes
Classical Exegesis
Complete liberation (kaivalyam), or the power (śaktiḥ) of consciousness (citi) firmly established (pratiṣṭhā) in its own true nature (sva-rūpa), occurs when the guṇas — the fundamental qualities of Prakṛti — return to their original source (pratiprasavaḥ). This return happens because they no longer serve any purpose (artha-śūnyānām) for Puruṣa (puruṣa). The final iti indicates the conclusion of this scripture
