The cause of the individual consciousness's conjunction with its buddhi is avidyā, explained here as a vāsanā of erroneous cognition. As long as buddhi has not attained knowledge of puruṣa, it has not completed its task and arises again. With perfected knowledge of puruṣa, the cause of bondage disappears, buddhi ceases its activity and does not return.

When non-seeing ends, the conjunction of buddhi and puruṣa and thus bondage end completely. This removal (hāna) is kaivalya for the seer: being unmixed and never again conjoined with the guṇa. When the cause of suffering has been removed, puruṣa abides in its own nature.

Viveka-khyāti is cognition of the difference between sattva and puruṣa. As long as erroneous knowledge persists, it wavers. Once that knowledge has become like a burned and sterile seed, a clear, uninterrupted stream of discrimination arises in sattva, purified of kleśa and rajas. It prevents erroneous knowledge from arising again and is the path to liberation.
