Kaivalya
kaivalyaLiberation: the word the Yoga Sutras end on. Rarely said in class, always implied.
The very last sutra of the whole text names the destination:
The resolution in the inverse order of the qualities, bereft of any motive of action for the Purusha, is Kaivalya, or it is the establishment of the power of knowledge in its own nature.
The original Sanskrit
puruṣārthaśūnyānāṃ guṇānāṃ pratiprasavaḥ kaivalyaṃ svarūpapratiṣṭhā vā citiśaktir iti
The translators render it as isolation: the Seer finally standing free of everything it is not. It is the tradition's word for the far end of the path this site keeps pointing down.
